Table 12. CTR(D)01h T8 and T16 Common Functions (Continued)
Mode
If the result is 0, the counter/timers are in the transmit mode; otherwise, they are in
the demodulation mode.
P36_Out/Demodulator_Input
In Transmit Mode, this bit defines whether P36 is used as a normal output pin or
the combined output of T8 and T16.
In Demodulation Mode, this bit defines whether the input signal to the Counter/
Timers is from P20 or P31.
T8/T16_Logic/Edge _Detect
In Transmit Mode, this field defines how the outputs of T8 and T16 are combined
(AND, OR, NOR, NAND).
In Demodulation Mode, this field defines which edge should be detected by the
edge detector.
Transmit_Submode/Glitch Filter
In Transmit Mode, this field defines whether T8 and T16 are in the Ping-Pong
mode or in independent normal operation mode. Setting this field to “Normal
Operation Mode” terminates the “Ping-Pong Mode” operation. When set to 10,
T16 is immediately forced to a 0; a setting of 11 forces T16 to output a 1.
In Demodulation Mode, this field defines the width of the glitch that must be fil-
tered out.
Initial_T8_Out/Rising_Edge
In Transmit Mode, if 0, the output of T8 is set to 0 when it starts to count. If 1, the
output of T8 is set to 1 when it starts to count. When the counter is not enabled
and this bit is set to 1 or 0, T8_OUT is set to the opposite state of this bit. This
