8.9
The INCA-D provides many possibilities to react on external asynchronous events by
using dedicated pins or a number of I/O lines for interrupt input.
For three of these pins either a positive, a negative, or both a positive and a negative
external transition can be selected to cause an interrupt or PEC service request (so
called Fast External Interrupts). For five of these pins (External Interrupts 3-7 at Port 2)
a rising edge, a falling edge or a detected high level on the interrupt request line cause
an interrupt or PEC request.

Pins T2IN or T4IN can be used as external interrupt input pins when the associated
auxiliary timer T2 or T4 in block GPT1 is configured for capture mode. This mode is
selected by programming the mode control fields T2M or T4M in control registers
T2CON or T4CON to 101
bit fields T2I or T4I. When these fields are programmed to X01
T2IR or T4IR in registers T2IC or T4IC will be set on a positive external transition at pins
T2IN or T4IN, respectively. When T2I or T4I are programmed to X10
external transition will set the corresponding request flag. When T2I or T4I are
programmed to X11
In all three cases, the contents of the core timer T3 will be captured into the auxiliary
timer registers T2 or T4 based on the transition at pins T2IN or T4IN. When the interrupt
