Auxiliary Interrupt Enable (AIE)
7 6 5 4 3 2 1 0 Reset Value
SFR A6h ESEC ESUM EADC EMSEC ESPIT ESPIR/EI2C EALV EDLVB 00h
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).
bit 7 Write: Set mask bit for this interrupt; 0 = masked, 1 = enabled.
Read: When AIPOL.RDSEL = 0: Current value of Seconds Timer Interrupt before masking.
When AIPOL.RDSEL = 1: Value of ESEC bit.
ESUM Enable Summation Interrupt.
bit 6 Write: Set mask bit for this interrupt; 0 = masked, 1 = enabled.
Read: When AIPOL.RDSEL = 0: Current value of Summation Interrupt before masking.
When AIPOL.RDSEL = 1: Value of ESUM bit.
EADC Enable ADC Interrupt.
bit 5 Write: Set mask bit for this interrupt; 0 = masked, 1 = enabled.
Read: When AIPOL.RDSEL = 0: Current value of ADC Interrupt before masking.
When AIPOL.RDSEL = 1: Value of EADC bit.
EMSEC Enable Millisecond System Timer Interrupt.
bit 4 Write: Set mask bit for this interrupt; 0 = masked, 1 = enabled.
Read: When AIPOL.RDSEL = 0: Current value of Millisecond System Timer Interrupt before masking.
When AIPOL.RDSEL = 1: Value of EMSEC bit.
ESPIT Enable SPI Transmit Interrupt.
bit 3 Write: Set mask bit for this interrupt; 0 = masked, 1 = enabled.
Read: When AIPOL.RDSEL = 0: Current value of SPI Transmit Interrupt before masking.
When AIPOL.RDSEL = 1: Value of ESPIT bit.
ESPIR/EI2C Enable SPI Receive Interrupt. Enable I
2
C Status Interrupt. (I
2
C available only on the MSC1213.)
bit 2 Write: Set mask bit for this interrupt; 0 = masked, 1 = enabled.
Read: When AIPOL.RDSEL = 0: Current value of SPI Receive Interrupt or I
2
C Status Interrupt before masking.
When AIPOL.RDSEL = 1: Value of ESPIR/EI2C bit.
EALV Enable Analog Low Voltage Interrupt.
bit 1 Write: Set mask bit for this interrupt; 0 = masked, 1 = enabled.
Read: When AIPOL.RDSEL = 0: Current value of Analog Low Voltage Interrupt before masking.
When AIPOL.RDSEL = 1: Value of EALV bit.
EDLVB Enable Digital Low Voltage or Breakpoint Interrupt (highest priority auxiliary interrupt).
bit 0 Write: Set mask bit for this interrupt; 0 = masked, 1 = enabled.
Read: When AIPOL.RDSEL = 0: Current value of Digital Low Voltage or Breakpoint Interrupt before masking.
When AIPOL.RDSEL = 1: Value of EDLVB bit.
