From Stop Mode Recovery Source of SMR
Two on-board comparators process analog signals on P31 and P32, with reference to the
voltage on Pref1 and P33. The analog function is enabled by programming the Port 3
Mode register (bit 1). P31 and P32 are programmable as rising, falling, or both edge
triggered interrupts (IRQ register bits 6 and 7). Pref1 and P33 are the comparator reference
voltage inputs. Access to the Counter Timer edge-detection circuit is through P31 or P20
