Program/Erase Commands

Program/erase commands are used to program or erase the user area or data area based on the response to inquiry
commands. Table 31.17 lists commands used in each of the program/erase host command wait state, program wait state,
and erase wait state. Table 31.18 lists commands that can be accepted in each state.
When a command that is not listed in Table 31.18 is received in each state, the MCU sends a command error response.

31.10.8.1 User/Data Area Program Preparation
This command is used to prepare for accepting the program command and the data area program command.
When the MCU receives this command, it recognizes that an instruction to prepare for the program command is issued
from the host. Then, the MCU enters the program wait state, where only the program command to the user area or data
area can be accepted, and sends a response (06h).
