The boot program returns information from the flash memory in response to the host’s inquiry
commands and sets the device code, clock mode, and bit rate in response to the host’s selection
command.
Inquiry and selection commands are listed below.
Table 20.11 Inquiry and Selection Commands
The selection commands, which are device selection (H'10), clock mode selection (H'11), and new
bit rate selection (H'3F), should be sent from the host in that order. These commands will certainly
be needed. When two or more selection commands are sent at once, the last command will be
valid.
All of these commands, except for the boot program status inquiry command (H'4F), will be valid
until the boot program receives the programming/erasing transition (H'40). The host can choose
