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 register controls the source of the timer signal when in internal mode. An 8-bit prescaler for each
counter is implemented. The control bit operate as follows:
CT0/CT1

010
011
100
101
110
111
Only the prescaler of CT1 is activated when the counters are cascaded.
