Data Sheet
Auxiliary Timer in Capture Mode
Capture mode for the auxiliary timers T2 and T4 is selected by setting bit field TxM in the
respective register TxCON to ‘101
latched into an auxiliary timer register in response to a signal transition at the respective
auxiliary timer's external input line TxIN. The capture trigger signal can be a positive, a
negative, or both a positive and a negative transition.
The two least significant bits of bit field TxI are used to select the active transition (see
table in the counter mode section), while the most significant bit TxI.2 is irrelevant for
capture mode. It is recommended to keep this bit cleared (TxI.2 = ‘0’).
Note: When programmed for capture mode, the respective auxiliary timer (T2 or T4)

Upon a trigger (selected transition) at the corresponding input line TxIN the contents of
the core timer are loaded into the auxiliary timer register and the associated interrupt
request flag TxIR will be set.
Note: The direction control for T2IN and for T4IN must be set to 'Input', and the level of
stops independent of its run flag T2R or T4R.
the capture trigger signal should be held high or low for at least 4 f
cycles before it changes to ensure correct edge detection.
