Bit 3: Line Decoder Status Register Interrupt Status (LDSR). This bit is set when any of the latched status
register bits in the B3ZS/HDB3 Line Decoder block are set and enabled for interrupt. When set, this bit causes an
interrupt if PORT.ISRIE:LDSRIE and GLOBAL.ISRIE:PnISRIE are both set. See Section 8.10.
Bit 2: LIU Status Register Interrupt Status (LIUSR). This bit is set when any of the latched status register bits in
the LIU block are set and enabled for interrupt. When set, this bit causes an interrupt if PORT.ISRIE:LIUSRIE and
GLOBAL.ISRIE: PnISRIE are both set. See Section 8.10.
Bit 1: BERT Status Register Interrupt Status (BSR). This bit is set when any of the latched status register bits in
the BERT block are set and enabled for interrupt. When set, this bit causes an interrupt if PORT.ISRIE:BSRIE and
GLOBAL.ISRIE: PnISRIE are both set. See Section 8.10.
Bit 0: Port Status Register Interrupt Status (PSR). This bit is set when any of the latched status register bits in
the port latched status register (PORT.SRL) are set and enabled for interrupt. When set, this bit causes an interrupt
if PORT.ISRIE:PSRIE and GLOBAL.ISRIE: PnISRIE are both set. See Section 8.10.
Bit 3: Line Decoder Status Register Interrupt Enable (LDSRIE). This bit is the interrupt enable for the
PORT.ISR:LDSR status bit.
Bit 2: LIU Status Register Interrupt Enable (LIUSRIE). This bit is the interrupt enable for the PORT.ISR:LIUSR
status bit.
Bit 1: BERT Status Register Interrupt Enable (BSRIE). This bit is the interrupt enable for the PORT.ISR:BSR
status bit.
Bit 0: Port Status Register Interrupt Enable (PSRIE). This bit is the interrupt enable for the PORT.ISR:PSR
status bit.
