TMP89FM46 Considerations for Using Both Mask ROM and Flash Products TMP89FM46 ・ Flash Memory Control Registers
Mask ROM products do not contain the flash memory control registers shown in the table below. Therefore, a program that accesses these registers operates differently between mask ROM and flash products. If you use a flash product to check the operation of a program written for a mask ROM product, be sure not to write instructions that access these registers in the program. Register Name
FLSCR1 FLSCR2 / FLSCRM FLSSTB SPCR Address
0x0FD0 0x0FD1 0x0FD2 0x0FD3 Mask ROM Product 89CM46, 89CH46
Not available Flash Product 89FM46, 89FH46
Available TMP89FM46
Precaution for Using the Emulation Chip (Development Tool)
・ Precaution for debugging the voltage detection circuit In debug using the RTE870/C1 In-Circuit Emulator (ICE mode) with the TMP89C900 mounted on it, no
interrupt is generated when the supply voltage rises to the detection voltage. Since the #!Undefined!# may operate differently, take account of this difference when debugging programs.
For detail, refer to the chapter of Voltage Detection Circuit.
