Table 17.2-1 Explanation of Functions of Each Bit in the Flash Memory Control Status Register (FMCS)

	Bit name	Description

	INTE:	Bit causing an interrupt (IRQB) to the CPU to be generated when writing into or erasing
	Causing an
	Causing an	from flash memory is completed.
bit7	interrupt to the	from flash memory is completed.
bit7	interrupt to the	An interrupt (IRQB) to the CPU is generated when both the INTE bit and RDYINT bit
	CPU to be
	CPU to be	are "1". If the INTE bit is "0", no interrupt is generated.
	generated bit	are "1". If the INTE bit is "0", no interrupt is generated.
	generated bit

		Bit for indicating operation status of flash memory.
		This bit is set to "1" when writing into or erasing from flash memory is completed. After
	RDYINT:	data has been written into or erased from flash memory and this bit has been set to "1",
bit6	Flash memory	subsequent data can be written into or erased from flash memory.
bit6	operation state	Writing "0" clears this bit with "0", while if "1" is written into this bit, it is ignored. This
	operation state
	indication bit	bit is set to "1" upon the termination of the flash memory automatic algorithm (see
		Section "17.3 Starting the Flash Memory Automatic Algorithm ". The read modifier
		write (RMW) command always reads "1" from this bit.

		Bit for write-enabling flash memory areas.
		When this bit is set to "1", a write instruction performed after a command sequence for a
	WE:	section from C000H to FFFFH (see Section "17.3 Starting the Flash Memory Automatic
bit5	WE:	Algorithm ") is issued writes data into a flash memory area. When this bit is set to "0", no
bit5	Write enable bit	write/erase signals are generated. This bit is used to start a command for writing data into
	Write enable bit
		or erasing data from flash memory.
		It is recommended that this bit be set to "0" to prevent data from being incorrectly written
		into flash memory, whenever there is no data to be written or erased.

		Bit for status checking for writing data into or erasing data from flash memory.
bit4	RDY:	No data can be written into or erased from flash memory while this bit is "0". However, a
bit4	ReaDY bit	read command, reset command, and suspend commands such as the sector erase suspend
	ReaDY bit
		command can be accepted while this bit is "0".

bit3		Reading / Writing for these bits have no effect.
