Capture Event Function
There are a number of interrupt events that can be captured by the general-purpose timers. These events are shown in Table 225. Any of
the events associated with a general-purpose timer can cause a capture of the 16-bit TxVAL register into the 16-bit TxCAP register.
TxCON has a 4-bit field selecting which of the events to capture.
When the selected interrupt event occurs, the TxVAL register is copied into the TxCAP register. TxSTA[1] is set, indicating that a capture
event is pending. The bit is cleared by writing 1 to TxCLRI[1]. The TxCAP register also holds its value and cannot be overwritten until a 1
is written to TxCLRI[1].
