Software Commands
Table 17 lists software commands. In the standard serial I/O mode,
erase operations, programs and reading are controlled by transfer-
ring software commands via the RxD pin. Software commands are

Notes 1:
Shading indicates transfer from flash memory microcomputer to peripheral unit. All other data is transferred from the peripheral
unit to the 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 (A

explained here below. Basically, the software commands of the
standard serial I/O mode is as same as that of the parallel I/O mode,
but it is excluded 1 command of block erase, and it is added 3 com-
mand of ID check, download function, version data output function.
