(iap) to update the user code in the internal 16 kbyte super- flash memory. all write/eras e operations require setting the enable bit in the superflash function register (sffr) located at 000bh. the following sections describe the operations that the mcu performs to alter the contents of superflash memory. for detailed explanation of the super- flash function register, pl ease refer to section 3.1. 5.1.1 chip-erase the chip-erase operation requires meren and mera bits to be set to logical ?1?. after setting these bits, writing any data to any address location of the flash memory will trigger the chip-erase operation. the mcu is idle while sst65p542r is busy doing erases on all memory loca- tions. 5.1.2 sector-erase the sector-erase operation requires seren and sera bits to be set to logical ?1?. after setting these bits, writing any data to the address within the sector to be erased will erase the data in the sector. the mcu is idle while sst65p542r is busy doing erase on the sector. 5.1.3 byte-program the byte-program operation requires pren and prog bits to be set to logical ?1?. after setting these bits, and then writing the data to the target address to be programmed. the mcu is idle while sst 65p542r is busy doing pro- gramming on the byte. refer to the following summary for all different functions. . 5.2 external host programming mode the external host programming mode is to provide pro- grammer access to the 16kb embedded flash memory of the sst65p542r. to enter the external host programming mode, users must follow the setup sequences on the pins (see figure 11-1): 1. ry/by# (pin 12) and porout# (pin 13) are out- put pins. do not drive. 2. drive rst# (pin 24) low. 3. drive lprst# (pin 21) low. 4. drive lprst# (pin 21) high after t rst . 5. drive prog_rst (pin 9) low. 6. drive 9 clocks on tclkin. on each clock's rising edge provide one bit of data on tdin (pin 19) as shown in figure 11-1. the data bits are ?11010011?. 7. wait for ry/by# (pin 12) and porout# to go high. 8. drive at least 24 clocks on tclkin. 9. if read-prote ct byte is set, then ry/by# will go low. otherwise, ry/by# will stay high. if ry/by# is low, wait for ry/by# (pin 12) to go high. now the sst65p542r is in external host programming mode and is ready for embedded flash read or write operations. now the sst65p542r is in the external host programming mode and is ready for embedded flash by the external host read or write. as soon as the rst# is released to ?1?, chip exits external host programming mode and then enters user mode. 5.2.1 external host mode read operation as shown in figure 11-2, the read operation needs two address setup cycles and one data setup cycle. the low to high transition on sclk la tches the high order address a[13:8] from the pin ad[5:0] while mode[1:0] inputs are set to 0h; the low to high transition on sclk latches the low order address a[7:0] from the pin ad[7:0] while the mode[1:0] inputs are set to 3h and setting the signal oe# to low; the low to high transition on sclk latches the data d[7:0] on the pin ad[7:0] while the mode[1:0] is set to 1h for reading. after reading the data, the external host should set the signal oe# to high. table 5-1: sffr c ommands function command writes to sffr comment chip-erase 44h erase the whole flash memory sector-erase 22h erase the sector addressed by cxxxh byte-program 88h program one data byte to address cxxxh. write data to cxxxh before byte-program can be performed, a chip-erase or sector-erase must be issued to erase the target programming locations. t5-1.1 1170

(see table 11-2) 6.4 cop watchdog timer reset sst65p542r has a cop (computer operating properly) watchdog timer for monitoring the proper operations of mcu. in normal operation, clearing the cop watchdog timer is executed by software within a preset period of time to avoid reaching time-out condition. to clear the cop watchdog timer, software write ?0? to location 3ff0h. the cop watchdog reset is asserted and resets the mcu when the time-out condition occurs. the cop watchdog timer is disabled during any external reset. to enable cwt, write logical ?0? to cwt control register (000dh). refer to the sst65p542r programming user?s manual for more information. 6.5 illegal address reset an illegal address reset is generated when the mcu attempts to fetch an instruction from i/o address space (0000h to 001fh). those addresses are reserved for i/o registers only. 1170 f16.2 osc a ddress rst# l prst# illegal address reset 4064 bus clock cycle delay cop watchdog reset reset control internal reset a ddress data
data sheet remote controller mcu sst65p542r 25 ?2005 silicon storage technology, inc. s71170-06-000 7/05 7.0 interrupts sst65p542r accepts five sources of interrupts with high- est to lowest priority: software interrupt, external interrupts (irq# pin / port b), cmt interrupt, and core timer inter- rupt. whenever multiple interrupt requests are active at the same time, the higher priority one will be serviced first. all interrupts are maskable except software interrupt which is generated by executing swi instruction. to mask inter- rupts, set the interrupt mask bit of process status word (psw). before serving the interrupt, the mcu registers are pushed onto the stack in the sequence of pcl, pch, idx, acc, psw. the interrupt service routine should clear the source of interrupt before exiting. by executing rti instruc- tion, the stored mcu registers are popped from the stack and the program resumes from the interrupted location. 7.1 software interrupt the swi instruction causes mcu to load the contents of memory locations fffch and fffdh into program counter regardless of the interrupt mask bit in psw register. 7.2 external interrupts upon completion of the current instruction, the mcu responds to the interrupt request that is latched internally. irq# must be asserted (low) for at least one t ilih (125 ns). following the completion of the current instruction, the interrupt latch is tested. if both interrupt mask bit (i bit) in the psw is clear and the interrupt request is pending, the inter- rupt service routine is entered. an external resistor to v dd is required by the irq# input for wired-and operation. the external interrupts, irq# pin and port b interrupts are edge-sensitive and asserted on the falling edge of the pins. the port b interrupt control register enables or disables interrupts on each individual pin of port b. the external interrupt mask bit (eimsk) of modulator control and sta- tus register can be used to mask all external interrupts so that lower priority interrupts such as timer interrupts can be served. the state of any external interrupt received during the masked period is preserved. when the eimsk bit is clear, the pending interrupts activate the mcu interrupt pro- cessing again. the external interrupt causes mcu to load the contents of memory lo cations fffah and fffbh into the program counter. 7.3 cmt interrupt a cmt interrupt is generated when the end of cycle flag (eoc) and the end of cycle interrupt enable (eocie) bits are set in the modulator control and status register (mcsr). this interrupt will vector to the interrupt service routine located at the addres s specified by the contents of memory locations fff8h and fff9h. 7.4 core timer interrupt the core timer is a 14-stage multifunctional ripple timer. user can select overflow or real-time interrupt by the setting of the core timer control status register. please see the timer section for more details. the timer interrupt causes mcu to load the contents of memory locations fff6h and fff7h into the program counter.
