(9) Programming/Erasing State
A programming selection command makes the boot program select the programming method, a
128-byte programming command makes it program the memory with data, and an erasing
selection command and block erasing command make it erase the block. The
programming/erasing commands are listed below.

Programming is executed by a programming-selection command and a 128-byte programming
command.
Firstly, the host should send the programming-selection command and select the programming
method and programming MATs. There are two programming selection commands, and
selection is according to the area and method for programming.
1. User boot MAT programming selection
