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.
