CTR2 (D)%02:
Counter/Timer16 Control Register.
CTR2 Description
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 terminal count is
reached. When set to 1, the counter stops when the termi-
nal 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 sub-
sequent edges. For details, see the description of T16 De-
modulation Mode.
Time_Out.
This bit is set when T16 times out (terminal
count reached). In order to reset it, a 1 should be written to
this location.
T16_Clock.
Defines the frequency of the input signal to
Counter/Timer16.
Capture_INT_Mask.
Set this bit to allow interrupt when
data is captured into LO16 and HI16.
Counter_INT_Mask.
Set this bit to allow interrupt when
T16 times out.
P35_Out.
This bit defines whether P35 is used as a normal
output pin or T16 output.
