pedl9041-03 1 semiconductor ml9041-xxa/xxb 14/60 functional description instruction register (ir), data register (dr), and expansion instruction register (er) these registers are selected by setting the level of the register selection input pins rs 0 and rs 1 . the dr is selected when both rs 0 and rs 1 are ?h?. the ir is selected when rs 0 is ?l? and rs 1 is ?h?. the er is selected when both rs 0 and rs 1 are ?l?. (when rs 0 is ?h? and rs 1 is ?l?, the ml9041 is not selected.) the ir stores an instruction code and sets the address code of the display data ram (ddram) or the character generator ram (cgram). the microcontroller (cpu) can write to the ir but cannot read from the ir. the er stores a contrast adjusting code and sets the address code of the arbitrator ram (abram). the cpu can write to or read from the er. the dr stores data to be written in the ddram, abram and cgram and also stores data read from the ddram, amram and cgram. the data written in the dr by the cpu is automatically written in the ddram, abram or cgram. when an address code is written in the ir or er, the data of the specified address is automatically transferred from the ddram, abram or cgram to the dr. the data of the ddram, abram and cgram can be checked by allowing the cpu to read the data stored in the dr. after the cpu writes data in the dr, the data of the next address in the ddram, abram or cgram is selected to be ready for the next writing by the cpu. similarly, after the cpu reads the data in the dr, the data of the next address in the ddram, abram or cgram is set in the dr to be ready for the next reading by the cpu. writing in or reading from these 3 registers is controlled by changing the status of the r/ w (read/write) pin. table 1 r/ w pin status and register operation r/ w rs 0 rs 1 operation l l h writing in the ir h l h reading the busy flag (bf) and the address counter (adc) l h h writing in the dr h h h reading from the dr l l l writing in the er h l l reading the contrast code busy flag (bf) the status ?1? of the busy flag (bf) indicates that the ml9041 is carrying out internal operation. when the bf is ?1?, any new instruction is ignored. when r/ w = ?h?, rs 0 = ?l? and rs 1 = ?h?, the data in the bf is output to the db 7 . new instructions should be input when the bf is ?0?. when the bf is ?1?, the output code of the address counter (adc) is undefined.
pedl9041-03 1 semiconductor ml9041-xxa/xxb 15/60 address counter (adc) the address counter provides a read/write address for the ddram, abram or cgram and also provides a cursor display address. when an instruction code specifying ddram, abram or cgram address setting is input to the pre-defined register, the register selects the specified ddram, abram or cgram and transfers the address code to the adc. the address data in the adc is automatically incremented (or decremented) by 1 after the display data is written in or read from the ddram, abram or cgram. the data in the adc is output to db 0 to db 6 when r/ w = ?h?, rs 0 = ?l?, rs 1 = ?h? and bf = ?0?. timing generator the timing generator generates timing signals for the internal operation of the ml9041 activated by the instruction sent from the cpu or for the operation of the internal circuits of the ml9041 such as ddram, abram, cgram and cgrom. timing signals are generated so that the internal operation carried out for lcd displaying will not be interfered by the internal operation initiated by accessing from the cpu. for example, when the cpu writes data in the ddram, the display of the lcd not corresponding to the written data is not affected.
pedl9041-03 1 semiconductor ml9041-xxa/xxb 16/60 display data ram (ddram) this ram stores the display data represented in 8-bit character coding (see table 2). the ddram addresses correspond to the display positions (digits) of the lcd as shown below. the ddram addresses (to be set in the adc) are represented in hexadecimal. msb lsb db 6 db 5 db 4 db 3 db 2 db 1 db 0 hexadecimal hexadecimal 2 0 a dc 0 1 0 0 1 0 1 a dc (example) representation of ddram address = 12 1) relationship between ddram addresses and display positions (1-line display mode) 00 01 02 03 04 12 13 digit 1 2 3 4 5 19 20 left end right end display position dd ram address (hexadecimal) in the 1-line display mode, the ml9041 can display up to 20 characters from digit 1 to digit 20. while the ddram has addresses ?00? to ?4f? for up to 80 character codes, the area not used for display can be used as a ram area for general data. when the display is shifted by instruction, the relationship between the lcd display and the ddram address changes as shown below: 4f 00 01 02 11 12 digit 1 234 1920 (display shifted to the right) 01 02 03 04 13 14 digit 1 234 05 51920 (display shifted to the left)

pedl9041-03 1 semiconductor ml9041-xxa/xxb 18/60 character generator rom (cgrom) the cgrom generates small character patterns (5 7 dots, 160 patterns) or large character patterns (5 10 dots, 32 patterns) from the 8-bit character code signals in the ddram. when the 8-bit character code corresponding to a character pattern in the cgrom is written in the ddram, the character pattern is displayed in the display position specified by the ddram address. character codes 20 to 7f and a0 to ff are contained in the character code area in the cg rom. character codes 20 to 7f and a0 to df are contained in the character code area for the 5 7-dot character patterns. character codes e0 to ff are contained in the rom area for 5 10-dot character patterns. the general character generator rom codes are 01a/01b. the relationship between character codes and general purpose character patterns are indicated in table2.
pedl9041-03 1 semiconductor ml9041-xxa/xxb 19/60 character generator ram (cgram) the cgram is used to generate user-specific character patterns that are not in the cgrom. cgram (64 bytes = 512 bits) can store up to 8 small character patterns (5 8 dots) or up to 4 large character patterns (5 11 dots). when displaying a character pattern stored in the cgram, write an 8-bit character code (00 to 07 or 08 to 0f; hex.) assigned in table 2 to the ddram. this enables outputting the character pattern to the lcd display position corresponding to the ddram address. the cursor or blink is also displayed even when a cgram or abram address is set in the adc. therefore, the cursor or blink display should be inhibited while the adc is holding a cgram or abram address. the following describes how character patterns are written in and read from the cgram. 1) small character patterns (5 8 dots) (see table 3-1.) (1) a method of writing character patterns to the cgram from the cpu the three cgram address bits 0 to 2 select one of the lines constituting a character pattern. first, set the mode to increment or decrement from the cpu, and then input the cgram address. write each line of the character pattern code in the cgram through db 0 to db 7 . the data lines db 0 to db 7 correspond to the cgram data bits 0 to 7, respectively (see table 3-1). input data ?1? represents the on status of an lcd dot and ?0? represents the off status. since the adc is automatically incremented or decremented by 1 after the data is written to the cgram, it is not necessary to set the cgram address again. the bottom line of a character pattern (the cgram address bits 0 to 2 are all ?1?, which means 7 in hexadecimal) is the cursor line. the on/off pattern of this line is ored with the cursor pattern for displaying on the lcd. therefore, the pattern data for the cursor position should be all zeros to display the cursor. whereas the data given by the cgram data bits 0 to 4 is output to the lcd as display data, the data given by the cgram data bits 5 to 7 is not. therefore, the cgram data bits 5 to 7 can be used as a ram area. (2) a method of displaying cgram character patterns on the lcd the cgram is selected when the higher-order 4 bits of a character code are all zeros. since bit 3 of a character code is not used, the character pattern ?0? in table 3-1 can be selected using the character code ?00? or ?08? in hexadecimal. when the 8-bit character code corresponding to a character pattern in the cgram is written to the ddram, the character pattern is displayed in the display position specified by the ddram address. (the ddram data bits 0 to 2 correspond to the cgram address bits 3 to 5, respectively.)
pedl9041-03 1 semiconductor ml9041-xxa/xxb 20/60 2) large character patterns (5 11 dots) (see table 3-2.) (1) a method of writing character patterns to the cgram from the cpu the four cgram address bits 0 to 3 select one of the lines constituting a character pattern. first, set the mode to increment or decrement from the cpu, and then input the cgram address. write each line of the character pattern code in the cgram through db 0 to db 7 . the data lines db 0 to db 7 correspond to the cgram data bits 0 to 7, respectively (see table 3-2). input data ?1? represents the on status of an lcd dot and ?0? represents the off status. since the adc is automatically incremented or decremented by 1 after the data is written to the cgram, it is not necessary to set the cgram address again. the bottom line of a character pattern (the cgram address bits 0 to 3 are all ?1?, which means a in hexadecimal) is a cursor line. the on/off pattern of this line is ored with the cursor pattern for displaying on the lcd. therefore, the pattern data for the cursor position should be all zeros to display the cursor. whereas the data given by the cgram data bits 0 to 4 with the cgram addresses 0 to a in hexadecimal (set by the cgram address bits 0 to 3) is output as display data to the lcd, the data given by the cgram data bits 5 to 7 or the cgram addresses b to f in hexadecimal is not. these bits can be written and read as a ram area. (2) a method of displaying cgram character patterns on the lcd the cgram is selected when the higher-order 4 bits of a character code are all zeros. since bits 0 and 3 of a character code are not used, the character pattern ? ? in table 3-2 can be selected with a character code ?00?, ?01?, ?08? or ?09? in hexadecimal. when the 8-bit character code corresponding to a character pattern in the cgram is written to the ddram, the character pattern is displayed in the display position specified by the ddram address. (the ddram data bits 1 and 2 correspond to the cgram address bits 4 and 5, respectively.)

pedl9041-03 1 semiconductor ml9041-xxa/xxb 29/60 built-in reset circuit the ml9041 is automatically initialized when the power is turned on. during initialization, the busy flag (bf) is ?1? and the ml9041 does not accept any instruction from the cpu (other than the read bf instruction). the busy flag is ?1? for about 15 ms after the v dd becomes 2.5 v or higher. during this initialization, the ml9041 performs the following instructions: 1) display clearing 2) cpu interface data length = 8 bits (dl = ?1?) 3) 1-line lcd display (n = ?0?) 4) font size = 5 7 dots (f = ?0?) 5) adc counting = increment (i/d = ?1?) 6) display shifting = none (s = ?0?) 7) display = off (d = ?0?) 8) cursor = off (c = ?0?) 9) blinking = off (b = ?0?) 10) arbitrator = displayed in the lower line (as = ?0?) 11) setting 1fh (hexadecimal) to the contrast data to use the built-in reset circuit, the power supply conditions shown below should be satisfied. otherwise, the built-in reset circuit may not work properly. in such a case, initialize the ml9041 with the instructions from the cpu. the use of a battery always requires such initialization from the cpu.

pedl9041-03 1 semiconductor ml9041-xxa/xxb 30/60 i/f with cpu parallel interface mode the ml9041 can transfer either 8 bits once or 4 bits twice on the data bus for interfacing with any 8-bit or 4-bit microcontroller (cpu). 1) 8-bit interface data length the ml9041 uses all of the 8 data bus lines db 0 to db 7 at a time to transfer data to and from the cpu. 2) 4-bit interface data length the ml9041 uses only the higher-order 4 data bus lines db 4 to db 7 twice to transfer 8-bit data to and from the cpu. the ml9041 first transfers the higher-order 4 bits of 8-bit data (db 4 to db 7 in the case of 8-bit interface data length) and then the lower-order 4 bits of the data (db 0 to db 3 in the case of 8-bit interface data length). the lower-order 4 bits of data should always be transferred even when only the transfer of the higher-order 4 bits of data is required. (example: reading the busy flag) two transfers of 4 bits of data complete the transfer of a set of 8-bit data. therefore, when only one access is made, the following data transfer cannot be completed properly.

(the entire display does not shift, but the cursor or blink shifts to the right (i/d = ?1?) or to the left (i/d = ?0?) by 1 character position.) when s = ?0?, the display does not shift, but normal write/read is performed. note: the execution time of this instruction is 37 s (maximum) at an oscillation frequency of 270 khz. 4) display mode setting rs 1 1 rs 0 0 r/ w 0 db 7 0 db 6 0 db 5 0 db 4 0 db 3 1 db 2 d db 1 c db 0 b instruction code: (1) the ?d? bit (db2) of this instruction determines whether or not to display character patterns on the lcd. when the ?d? bit is ?1?, character patterns are displayed on the lcd. when the ?d? bit is ?0?, character patterns are not displayed on the lcd and the cursor/blink setting is also canceled. note: unlike the display clear instruction, this instruction does not change the character code in the ddram and abram. (2) when the ?c? bit (db1) is ?0?, the cursor turns off. when both the ?c? and ?d? bits are ?1?, the cursor turns on. (3) when the ?b? bit (db0) is ?0?, blinking is canceled. when both the ?b? and ?d? bits are ?1?, blinking is performed. in the blinking mode, all dots including those of the cursor, the character pattern and the cursor are alternately displayed. note: the execution time of this instruction is 37 s (maximum) at an oscillation frequency of 270 khz.
