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 RxD
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.
