This command reads the flash memory.
By writing command code ‘xxFF
specified address can be read in 16-bit unit after the next bus cycle. The microcomputer remains in
read array mode until an another command is written. Therefore, contents of multiple addresses can
be read consecutively.
This command reads the status register.
