This 16-bit register pair is used to hold the counter value saved when using the "capture on external
event" function. This register will capture at the rising edge of the I/O pin or when software capture is
asserted. When the bi-value mode of operation is enabled, this register is used as a second Time Constant
register and the counter is alternately loaded from each.

Initial Value
Read/Write
This 16-bit register pair holds the value that is automatically loaded into the counter/timer (1) when the
counter/timer is enabled, (2) when the count reaches zero in continuous mode or (3) when the trigger is
asserted in re-trigger mode. If capture on both edges is enabled, this register captures the contents of the
counter on the falling edge of the I/O pin.
