Data Sheet
enable bits T2IE or T4IE are set, a PEC request or an interrupt request for vector T2INT
or T4INT will be generated.
Note: The non-maskable interrupt input pin NMI and the reset input RSTIN provide
Regular External Interrupts at P2.3-7
The input pins that may be used for regular external interrupts are sampled every
16 TCL, ie. external events are scanned and detected in timeframes of 16 TCL. These
five pins of Port 2 (P2.3...P2.7) can individually be programmed to determine the
sensitivity, i.e. rising, falling or level sensitivity can be selected.

Fast External Interrupts
The INCA-D provides the capability to sample selected interrupt pins every 2 TCL, so
external events are captured faster than with standard interrupt inputs.
Three pins of Port 2 (P2.2...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 3 pins.

another possibility for the CPU to react on an external input signal. NMI and RSTIN
are dedicated input pins, which cause hardware traps.
