The other interrupts are controlled by the IE and EIE registers. ESEC Enable Second System Timer Interrupt (lowest priority auxiliary interrupt). bit 7 Write: Set mask bit for this interrupt; 0 = masked, 1 = enabled. Read: Second Timer Interrupt mask. ESUM Enable Summation Interrupt. bit 6 Write: Set mask bit for this interrupt; 0 = masked, 1 = enabled. Read: Summation Interrupt mask. EADC Enable ADC Interrupt. bit 5 Write: Set mask bit for this interrupt; 0 = masked, 1 = enabled. Read: ADC Interrupt mask. EMSEC Enable Millisecond System Timer Interrupt. bit 4 Write: Set mask bit for this interrupt; 0 = masked, 1 = enabled. Read: Millisecond System Timer Interrupt mask. EI2C Enable I2C Start/Stop Bit. bit 3 Write: Set mask bit for this interrupt; 0 = masked, 1 = enabled. Read: I2C Start/Stop Bit mask. ECNT Enable Serial Bit Count Interrupt. bit 2 Write: Set mask bit for this interrupt; 0 = masked, 1 = enabled. Read: Serial Bit Count Interrupt mask. EALV Enable Analog Low Voltage Interrupt. bit 1 Write: Set mask bit for this interrupt; 0 = masked, 1 = enabled. Read: Analog Low Voltage Detect Interrupt mask. 7 6 5 4 3 2 1 0 Reset Value SFR A5H 0 0 0 0 PAI3 PAI2 PAI1 PAI0 00H PAI3 PAI2 PAI1 PAI0 AUXILIARY INTERRUPT STATUS 0 0 0 0 No Pending Auxiliary IRQ 0 0 0 1 Reserved 0 0 1 0 Analog Low Voltage Detect IRQ and Possible Lower Priority Pending 00 1 1 I2C IRQ and Possible Lower Priority Pending 0 1 0 0 Serial Bit Count Interrupt and Possible Lower Priority Pending 0 1 0 1 Millisecond System Timer IRQ and Possible Lower Priority Pending 0 1 1 0 ADC IRQ and Possible Lower Priority Pending 0 1 1 1 Accumulator IRQ and Possible Lower Priority Pending 1 0 0 0 Second System Timer IRQ and Possible Lower Priority Pending Pending Auxiliary Interrupt (PAI) PAI Pending Auxiliary Interrupt Register. The results of this register can be used as an index to vector to the appropriate bits 3-0 interrupt routine. All of these interrupts vector through address 0033H. |
