: Write data (8-bit)
The software commands are described below. Read or write commands and data in 8-bit units. However, write
the command and data of the program (word units) in 16-bit units.
The read array command is used to read the flash memory.
When FFh is written in the first bus cycle, the MCU enters read array mode. When the read address is input in
the following bus cycles, the content of the specified address can be read in 8-bit units.
Since read array mode remains until another command is written, the contents of multiple addresses can be read
continuously.
In addition, after a reset, the MCU enters read array mode after programming or block erasure or after entering
erase-suspend.
The clear status register command is used to set bits FST4 and FST5 in the FST register to 0.
When 50h is written in the first bus cycle, bits FST4 and FST5 in the FST register are set to 0.
: Write data (16-bit)
Command
Write address (specify the even address to program in word units.)
Any block address
Starting block address
Upper eight bits of command code (these bits are ignored)
Any address in the user ROM area
