Bit 7
CTnPAU
: CTMn Counter Pause control
0: Run
1: Pause
The counter can be paused by setting this bit high. Clearing the bit to zero restores
normal counter operation. When in a Pause condition the CTMn will remain powered
up and continue to consume power. The counter will retain its residual value when
this bit changes from low to high and resume counting from this value when the bit
changes to a low value again.

110: CTCKn rising edge clock
111: CTCKn falling edge clock
These three bits are used to select the clock source for the CTMn. The external pin
clock source can be chosen to be active on the rising or falling edge. The clock source
f
SYS
is the system clock, while f
H
and f
SUB
are other internal clocks, the details of which
can be found in the oscillator section.
Bit 3
CTnON
: CTMn Counter On/Off control
0: Off
1: On
This bit controls the overall on/off function of the CTMn. Setting the bit high enables
the counter to run while clearing the bit disables the CTMn. Clearing this bit to zero
will stop the counter from counting and turn off the CTMn which will reduce its power
consumption. When the bit changes state from low to high the internal counter value
will be reset to zero, however when the bit changes from high to low, the internal
counter will retain its residual value until the bit returns high again. If the CTMn is in
the Compare Match Output Mode then the CTMn output pin will be reset to its initial
condition, as specified by the CTnOC bit, when the CTnON bit changes from low to
high.
