T16_Enable
This field enables T16 when set to 1.
Single/Modulo-N
In Transmit Mode, when set to 0, the counter reloads the initial value when termi-
nal count is reached. When set to 1, the counter stops when the terminal count is
reached.
In Demodulation Mode, when set to 0, T16 captures and reloads on detection of
all the edges. When set to 1, T16 captures and detects on the first edge, but
ignores the subsequent edges. For details, see the description of T16 Demodula-
tion Mode on page 45.
Time_Out
This bit is set when T16 times out (terminal count reached). To reset the bit, write
a 1 to this location.
T16_Clock
This bit defines the frequency of the input signal to Counter/Timer16.
Capture_INT_Mask
This bit is set to allow an interrupt when data is captured into LO16 and HI16.
