Notes 1: For this bit to be set to “1”, the user needs to write a “0” and then a
“1” to it in succession. For this bit to be set to “0”, write “0” only to
this bit.
2: Effective only when the suspend enable bit = “1”.

Flash memory control register 1
(FMCR1: address : 0FE116: initial value: 4016)
Figure 99 shows the flash memory control register 1.
Bit 0 of the flash memory control register 1 is the Erase suspend
enable bit. By setting this bit to “1”, the erase suspend mode to
suspend erase processing temporarily when block erase com-
mand is executed can be used. In order to set this bit to “1”,
writing “0” and “1” in succession to bit 0. In order to set this bit to
“0”, write “0” only to bit 0.
Bit 1 of the flash memory control register 1 is the erase suspend
request bit. By setting this bit to “1” when erase suspend enable
bit is “1”, the erase processing is suspended.
Bit 6 of the flash memory control register 1 is the erase suspend
flag. This bit is cleared to “0” at the flash erasing.
Figure 100 shows the flash memory control register 2.
Bit 0 of the flash memory control register 1 is the all user block E/
W enable bit. By setting this bit to “0”, Erase/Write to all user block
(blocks 0, 1, 2) is disabled. As a result, error writing in program to
write only to data block can be prevented.
