The read array command reads the flash memory.
Read array mode is entered by writing command code ‘xxFF
fied 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 con-
secutively.
The read status register command reads the status register.
By writing command code ‘xx70
