Table 40 describes the priority control for IRQ1. The IRQ1 Enable High and Low Bit reg-
isters (Tables 41 and 42) form a priority encoded enabling for interrupts in the Interrupt
Request 1 register. Priority is generated by setting bits in each register.
PA7VENH—Port A Bit[7] Interrupt Request Enable High Bit
PA6CENH—Port A Bit[7] or Comparator Interrupt Request Enable High Bit
PAxENH—Port A Bit[x] Interrupt Request Enable High Bit
Refer to the Shared Interrupt register for selection of Port A as the interrupt source.
where x indicates the register bits from 0–7.
