CTR2 Description
T16_Clock. Defines the frequency of the input signal to
T16_Enable. This field enables T16 when set to 1.
Counter/Timer16.
Single/Modulo-N. In Transmit Mode, when set to 0, the
counter reloads the initial value when terminal count is
Capture_INT_Mask. Set this bit to allow interrupt when
data is captured into LO16 and HI16.
1
reached. When set to 1, the counter stops when the termi-
nal count is reached.
Counter_INT_Mask. Set this bit to allow interrupt when
T16 times out.
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.
P35_Out. This bit defines whether P35 is used as a normal
output pin or T16 output.
Port pins configured as outputs are ignored as an SMR2
recover source. For example, if NAND of P23-P20 is se-
lected as the recover source and P20 is configured as out-
put, then P20 is ignored as a recover source. The effective
recover source in this case is NAND of P23-P21.
