Software Commands
Table 15 lists software commands. In standard serial I/O mode,
erase, program and read are controlled by transferring software
commands via the RxD pin. Software commands are explained

transfer
Notes1: Shading indicates transfer from the internal flash memory microcomputer to a programmer. All other data is transferred from a programmer to the in-
ternal flash memory microcomputer.
2: SRD refers to status register data. SRD1 refers to status register 1 data.
3: All commands can be accepted when the flash memory is totally blank.
4: “Address (high)” means A16 to A23 and are always set to “0016”.
“Address (middle)” means A8 to A15.
“Address (low)” means A0 to A7.
here below. Basically, the software commands of the standard se-
rial I/O mode are the same as that of the parallel I/O mode, but 4
commands are added: ID check, download, version data output
and Boot ROM area output functions.
