22.7 Memory Mapping
Figure 22-3 shows memory maps in serial PROM and MCU modes.
In serial PROM mode, the BOOTROM (mask ROM) is mapped to the 0x1000 through 0x17FF in the data area
and 0x1000 through 0x1FFF in the code area respectively.
To write data to or erase data from flash memory by using the RAM loader command (hereafter called the 0x60
command) and an original program, data write or erase operations must be performed while switching between areas
by using the flash memory control registers (FLSCR1 and 2). For information on how to specify addresses, refer to
Flash Memory.
When the command to write data to flash memory (hereafter called the 0x30 command) or the command to erase
data from flash memory (hereafter called the 0xF0 command) is executed, BOOTROM automatically converts
addresses. Therefore, as the address of flash memory, specify an address equivalent to that specified in MCU mode
(if FLSCR1<BAREA>="0"), namely, 0x8000 through 0xFFFF.

22.8 Operation Commands
In serial PROM mode, the commands shown in Table 22-5 are used. After a reset is released, the TMP89FM42
goes into a standby state and awaits the arrival of matching data 1 (0x86 or 0x30).
