17.11 Interfaces of the CAPCOM Units
The CAPCOM units CAPCOM1 (see Figure 17-14) and CAPCOM2 (see Figure 17-15)
are connected to their environment in different ways.
Internal Connections
The overflow/underflow signal T6OUF of GPT2 timer T6 is connected to the CAPCOM
units, providing an optional clock source for the CAPCOM timers.
The 18 interrupt request lines of each CAPCOM unit are connected to the interrupt
control block.
Note: The upper 8 input lines from PORT1, connected with the CAPCOM2 unit, can also
be used as individual external interrupt inputs.
The interrupt request line of channel 31 is connected to the ADC, as a possible trigger
source for injected conversions.
External Connections
Twelve capture/compare signals of the CAPCOM2 unit are connected with input/output
ports of the XC164. Depending on the selected direction, these ports may provide
capture trigger signals from the external system or issue compare output signals to
external circuitry.
Note: Capture trigger signals may also be derived from output pins. In this case,
software can generate the trigger edges, for example.
Timer T0 can be clocked by an external signal.
