Read Interrupt (RI)

This is the Read interrupt bit.

RI Interrupt [7]

Status	Conditions	Default State			Valid	Interrupt
Status	Conditions	Cold		Warm/hot	State	Function
		Cold		Warm/hot	State	Function
		1		0	0	off

	At the completion of a Load, Superload or LSB Page				0→1	Pending
sets itself to ‘1’	Recovery Read Operation.				0→1	Pending
	(0000h, 0003h or 0005h)

	‘0’ is written to this bit,
clears to ‘0’	Cold/Warm/Hot reset is being performed, or				1→0	off
clears to ‘0’	command is written to Command Register in INT auto				1→0	off
	command is written to Command Register in INT auto
	mode

Write Interrupt (WI)

This is the Write interrupt bit.

WI Interrupt [6]

	Status	Conditions	Default State		Valid	Interrupt
	Status	Conditions	Cold	Warm/hot	State	Function
			Cold	Warm/hot	State	Function
			0	0	0	off

	sets itself to ‘1’	At the completion of an Program Operation			0→1	Pending
	sets itself to ‘1’	(0080h and 007Fh)			0→1	Pending
		(0080h and 007Fh)

		‘0’ is written to this bit,
	clears to ‘0’	Cold/Warm/Hot reset is being performed, or com-			1→0	off
	clears to ‘0’	mand is written to Command Register in INT auto			1→0	off
		mand is written to Command Register in INT auto
		mode

Erase Interrupt (EI)

This is the Erase interrupt bit.

EI Interrupt [5]

	Status	Conditions	Default State		Valid	Interrupt
	Status	Conditions	Cold	Warm/hot	State	Function
			Cold	Warm/hot	State	Function
			0	0	0	off

	sets itself to ‘1’	At the completion of an Erase Operation			0→1	Pending
	sets itself to ‘1’	(0094h and 0030h)			0→1	Pending
		(0094h and 0030h)

		‘0’ is written to this bit,
	clears to ‘0’	Cold/Warm/Hot reset is being performed, or com-			1→0	off
	clears to ‘0’	mand is written to Command Register in INT auto			1→0	off
		mand is written to Command Register in INT auto
