Auxiliary interrupts are enabled by EICON.4 (SFR D8h); other interrupts are enabled by the IE and EIE registers.
ESEC Enable Seconds Timer Interrupt (lowest priority auxiliary interrupt). Read-only.
bit 7 AIPOL.RDSEL = 1: Read: Current value of Seconds Timer Interrupt before masking.
AIPOL.RDSEL = 0: Read: Value of ESEC bit.
ESUM Enable Summation Interrupt. Read-only.
bit 6 AIPOL.RDSEL = 1: Read: Current value of Summation Interrupt before masking.
AIPOL.RDSEL = 0: Read: Value of ESUM bit.
EADC Enable ADC Interrupt. Read-only.
bit 5 AIPOL.RDSEL = 1: Read: Current value of ADC Interrupt before masking.
AIPOL.RDSEL = 0: Read: Value of EADC bit.
EMSEC Enable Millisecond System Timer Interrupt. Read-only.
bit 4 AIPOL.RDSEL = 1: Read: Current value of Millisecond System Timer Interrupt before masking.
AIPOL.RDSEL = 0: Read: Value of EMSEC bit.
ESPIT Enable SPI Transmit Interrupt. Read-only.
bit 3 AIPOL.RDSEL = 1: Read: Current value of Enable SPI Transmit Interrupt before masking.
AIPOL.RDSEL = 0: Read: Value of ESPIT bit.
ESPIR/EI2C Enable SPI Receive Interrupt. Enable I2C Status Interrupt (I
2
C available only on the MSC1213). Read-only.
bit 2 AIPOL.RDSEL = 1: Read: Current value of Enable SPI Receive Interrupt or I2C Status Interrupt before masking.
AIPOL.RDSEL = 0: Read: Value of ESPIR/EI2C bit.
EALV Enable Analog Low Voltage Interrupt. Read-only.
bit 1 AIPOL.RDSEL = 1: Read: Current value of Enable Analog Low Voltage Interrupt before masking.
AIPOL.RDSEL = 0: Read: Value of EALV bit.
EDLVB Enable Digital Low Voltage or Breakpoint Interrupt (highest priority auxiliary interrupt). Read-only.
bit 0 AIPOL.RDSEL = 1: Read: Current value of Enable Digital Low Voltage or Breakpoint Interrupt before masking.
AIPOL.RDSEL = 0: Read: Value of EDLVB bit.
RDSEL Read Select. Write-only.
bit 0 AIPOL.RDSEL = 1: Read state for AIE and AIPOL registers. Reading AIPOL register gives current value of
Auxiliary interrupts before masking. Reading AIE register gives value of AIE register contents.
AIPOL.RDSEL = 0: Read state for AIE and AIPOL registers. Reading AIPOL register gives value of AIE register
contents. Reading AIE register gives current value of Auxiliary interrupts before masking.
