LPC above interrupt flag

[Clearing conditions]

• Writing 0 after reading ABRT = 1

• LPC hardware reset (

LRESET pin falling edge detection)

• LPC software reset (LRSTB = 1)

• LPC hardware shutdown (SDWNE = 1 and

LPCPD falling edge detection)

• LPC software shutdown (SDWNB = 1)

[Setting condition]

•

LFRAME pin falling edge detection during LPC transfer cycle

LPC shutdown interrupt flag

Note: * Only 0 can be written to bits 6 to 4, to clear the flags.

[Clearing conditions]

• Writing 0 after reading SDWN = 1

• LPC hardware reset (

LRESET pin falling edge detection)

• LPC software reset (LRSTB = 1)

[Setting condition]

•

LPCPD pin falling edge detection

LPC reset interrupt flag

[Clearing condition]

• Writing 0 after reading LRST = 1

[Setting condition]

•

LRESET pin falling edge detection
