Software Commands

Table 1.23.2 lists software commands. In the standard serial I/O mode 2, erase operations, programs

and reading are controlled by transferring software commands via the RxD1 pin. Standard serial I/O

mode 2 adds four transmission speed commands - 9,600, 19,200, 38,400 and 57,600 bps - to the soft-

ware commands of standard serial I/O mode 1. Software commands are explained here below.

Table 1.23.2. Software commands (Standard serial I/O mode 2) (Note 1)

Note 1: All commands can be accepted when the flash memory is totally blank.

Note 2: Shading indicates transfer from flash memory microcomputer to peripheral unit. All other data is

transferred from the peripheral unit to the flash memory microcomputer.

Note 3: SRD refers to status register data. SRD1 refers to status register 1 data.

Note 4: The 'erase all' command does not erase the Flash data blocks.
