SEC
Second System Timer Interrupt Status Flag (lowest priority AI).
bit 7
0: SEC interrupt inactive or masked.
1: SEC Interrupt active. (It is set inactive by reading the SECINT register.)
SUM
Summation Register Interrupt Status Flag.
bit 6
0: SUM interrupt inactive or masked.
1: SUM interrupt active. (It is set inactive by reading the lowest byte of the Summation register.)
ADC
ADC Interrupt Status Flag.
bit 5
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
Millisecond System Timer Interrupt Status Flag.
bit 4
0: MSEC interrupt inactive or masked.
1: MSEC interrupt active. (It is set inactive by reading the MSINT register.)
SPIT
SPI Transmit Interrupt Status Flag.
bit 3
0: SPI transmit interrupt inactive or masked.
1: SPI transmit interrupt active. (It is set inactive by writing to the SPIDATA register.)
SPIR
SPI Receive Interrupt Status Flag.
bit 2
0: SPI receive interrupt inactive or masked.
1: SPI receive interrupt active. (It is set inactive by reading from the SPIDATA register.)
ALVD
Analog Low Voltage Detect Interrupt Status Flag.
bit 1
0: ALVD interrupt inactive or masked.
1: ALVD interrupt active. (Interrupt stays active until the AVDD voltage exceeds the threshold.)
DLVD
Digital Low Voltage Detect or Breakpoint Interrupt Status Flag (highest priority AI).
bit 0
0: DLVD interrupt inactive or masked.
1: DLVD interrupt active. (Interrupt stays active until the DVDD voltage exceeds the threshold or the Breakpoint is
cleared.)
