SEC
bit 7
Second System Timer Interrupt Status Flag (lowest priority AI).
0: SEC interrupt inactive or masked.
1: SEC Interrupt active.
SUM
bit 6
Summation Register Interrupt Status Flag.
0: SUM interrupt inactive or masked (if active, it is set inactive by reading the lowest byte of the Summation register).
1: SUM interrupt active.
ADC
bit 5
ADC Interrupt Status Flag.
0: ADC interrupt inactive or masked (If active, it is set inactive by reading the lowest byte of the Data Output Register).
1: ADC interrupt active (If active no new data will be written to the Data Output Register).
MSEC
bit 4
Millisecond System Timer Interrupt Status Flag.
0: MSEC interrupt inactive or masked.
1: MSEC interrupt active.
SPIT
bit 3
SPI Transmit Interrupt Status Flag.
0: SPI transmit interrupt inactive or masked.
1: SPI transmit interrupt active.
SPIR/I2CSI SPI Receive Interrupt Status Flag. I²C Status Interrupt. (I²C available only on the MSC1213.)
bit 2
0: SPI receive or I2CSI interrupt inactive or masked.
1: SPI receive or I2CSI interrupt active.
ALVD
bit 1
Analog Low Voltage Detect Interrupt Status Flag.
0: ALVD interrupt inactive or masked.
1: ALVD interrupt active.
DLVD
bit 0
Digital Low Voltage Detect or Breakpoint Interrupt Status Flag (highest priority AI).
0: DLVD interrupt inactive or masked.
1: DLVD interrupt active.
