7.8.1
The input pins that may be used for external interrupts are sampled every 16 TCL, ie.
external events are scanned and detected in timeframes of 16 TCL. C161U provides 2
external interrupt inputs that are sampled every 2 TCL, so external events are captured
faster than with standard interrupt inputs.
The pins of Port 2 (P2.1...P2.0) can individually be programmed to this fast interrupt
mode, where also the trigger transition (rising, falling or both) can be selected. The
External Interrupt Control register EXICON controls this feature for all 8 pins.
