8 Bit Microcontroller TLCS-870/C1 Series TMP89FM42 © 2009 TOSHIBA CORPORATION All Rights Reserved Considerations for Using Both Mask ROM and Flash Products TMP89FM42 ・ 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 89CM42, 89CH42 Not available Flash Product 89FM42, 89FH42 Available ・ Conversion Accuracy of the AD Converter The conversion accuracy of the AD converter differs between mask ROM and flash products, as shown below. When developing your application system, careful consideration must be given to these accuracy differences.
