RL78 family eeprom emulation library pack0 2 ver.1. 01 release note r20ut2645ej0100 rev.1.00 p age 14 of 15 mar 28, 2014 8.3 definition of the on - chip ram area this section describes how t he on- chip ram area is defined in the link directive file. normally, the entire on - chip ram area is automatically defined as "ram" unless otherwise stated in the link directive file. stacks are to be allocated t o "ram" except as otherwise noted note . however, in this case, stacks or data b uffers are allocated to an area (self - ram or ffe20h to ffeffh) that is prohibited to be used by the eeprom emulation library pack02 and the program may not operate correctly. in the attached link directive file for the sample program, as a solution , "ram" is re - defined not to include the area which the eeprom emulation library pack02 is prohibited to use so that stacks or data buffers are not allocated to that area. in the abo ve code, "ram" is re - defined to be an area (ff300h to ffe1fh) note with a size of b20h bytes and starting from address ff300h. this prevents the area which the eeprom emulation library pack02 is prohibited to use from being included in "ram". however, if on ly this setting is made, the area of "ffe20h to ffeffh" cannot be used for any other purposes either. therefore, the following definition must be added separately. there are no particular restrictions regarding the name of this area. if there is a self - ram area, by defining its range with the name of "selfram", automatic allocation of variables to this area can be restricted. a setting example for the RL78/g13 (product with 4 - kbyte ram and 6 4 - kbyte rom ) is given below. note: the ca7 8k0r linker allocates data whose allocation destination is not specified (segment type of dseg or bseg) to the on - chip ram area according to the re- allocation attribute of the data. accordingly, specific data may not be allocated to the area with the name of "ram" in some situations. for details on the definition or allocation method of each data, refer to the user's manual of the cubesuite+. the map file (*.map) generated at build must be referenced to confirm the allocation state. memory ram :(0ff300h, 000b20h) ; ---------------------------------------------------------- ; define new memory entry for self - ram ; ------------------------------------------- --------------- memory selfram : ( 0fef00h, 000400h ) definition of the self - ram area ; ---------------------------------------------------------- ; redefined default data segment ram ; ---------------------------------------------------------- me mory ram : ( 0ff300h, 000b20h ) definition of the ram area to be used normally ; ---------------------------------------------------------- ; define new memory entry for saddr area ; ---------------------------------------------------------- m emory ram_saddr : ( 0ffe20h, 0001e0h ) definitio n of the area from ffe20h to ff f ffh memory saddr_ram:(0ffe20h, 0001e0h) memory selfram :(0fef00h, 000400h)

general precautions in the handling of mpu/mcu products the following usage notes are applicab le to all mpu/mcu products from renesas. for detailed usage notes on the products covered by this document, refer to the relevant sections of the document as well as any technical updates that have been issued for the products. 1. handling of unused pins handle unused pins in accordance with the directions given under handling of unused pins in the manual. ? the input pins of cmos products are generally in the high - impedance state. in operation with an unused pin in the open - circuit state, extra electromagn etic noise is induced in the vicinity of lsi, an associated shoot - through current flows internally, and malfunctions occur due to the false recognition of the pin state as an input signal become possible. unused pins should be handled as described under ha ndling of unused pins in the manual. 2. processing at power - on the state of the product is undefined at the moment when power is supplied. ? the states of internal circuits in the lsi are indeterminate and the states of register settings and pins are undefi ned at the moment when power is supplied. in a finished product where the reset signal is applied to the external reset pin, the states of pins are not guaranteed from the moment when power is supplied until the reset process is completed. in a similar way , the states of pins in a product that is reset by an on - chip power - on reset function are not guaranteed from the moment when power is supplied until the power reaches the level at which resetting has been specified. 3. prohibition of access to reserved a ddresses access to reserved addresses is prohibited. ? the reserved addresses are provided for the possible future expansion of functions. do not access these addresses; the correct operation of lsi is not guaranteed if they are accessed. 4. clock signals a fter applying a reset, only release the reset line after the operating clock signal has become stable. when switching the clock signal during program execution, wait until the target clock signal has stabilized. ? when the clock signal is generated with an e xternal resonator (or from an external oscillator) during a reset, ensure that the reset line is only released after full stabilization of the clock signal. moreover, when switching to a clock signal produced with an external resonator (or by an external o scillator) while program execution is in progress, wait until the target clock signal is stable. 5. differences between products before changing from one product to another, i.e. to a product with a different part number, confirm that the change will not lead to problems. ? the characteristics of an mpu or mcu in the same group but having a different part number may differ in terms of the internal memory capacity, layout pattern, and other factors, which can affect the ranges of electrical characteristics, s uch as characteristic values, operating margins, immunity to noise, and amount of radiated noise. when changing to a product with a different part number, implement a system - evaluation test for the given product.
