M16C/62P Group, R32C/111 Group

Differences between M16C/62P and R32C/111 (100 pin ver.)

4.19 Flash Memory

4.19.1 Flash Memory

Table 4.49 to Table 4.51 respectively list the changes on flash memory, software commands, and

associated registers.

WA: Even address to be written

WD: 16-bit write data

BA: Even address in specified block

PBA: Address of the protect bit

x: Any even address in the user ROM area

xx: Upper byte of command code (ignored)

N/A: Not applicable

Notes:

1. This command cannot be executed in EW1 mode.

2. In the M16C/62P, a set of command consists of two words from the first command to the second. The

program is performed in 16-bit (1-word) unit.

3. In the R32C/111, a set of command consists of five words from the first command to the fifth. The

program is performed in 64-bit (4-word) unit. The higher 29 bits of the address WA should be fixed

and the lower three bits of respective command from the second to fifth should be set to 000b, 010b,

100b, and 110b for the addresses 0h, 2h, 4h, and 6h, or 8h, Ah, Ch, and Eh.

4. This command should be executed in RAM.
