Figure 50. T8 and T16 Common Control Functions—(0D) 1H: Read/Write
Transmit Mode
R/W 0 T16_OUT is 0 initially
Demodulation Mode
R 0 = No Falling Edge Detection
R 1 = Falling Edge Detection
W 0 = No Effect
W 1 = Reset Flag to 0
Transmit Mode
R/W 0 = T8_OUT is 0 initially
R/W 1 = T8_OUT is 1 initially
Demodulation Mode
R 0 = No Rising Edge Detection
R 1 = Rising Edge Detection
W 0 = No Effect
W 1 = Reset flag to 0
Transmit Mode
0 0 = Normal Operation
0 1 = Ping-Pong Mode
1 0 T16_OUT = 0
1 1 T16_OUT = 1
Demodulation Mode
0 0 = No Filter
0 1 = 4 SCLK Cycle Filter
1 0 = 8 SCLK Cycle Filter
1 1 = Reserved
Transmit Mode/T8/T16 Logic
0 0 = AND
0 1 = OR
1 0 = NOR
1 1 = NAND
Demodulation Mode
0 0 = Falling Edge Detection
0 1 = Rising Edge Detection
1 0 = Both Edge Detection
1 1 = Reserved
Transmit Mode
0 = P36 as Port Output *
1 = P36 as T8/T16_OUT
Demodulation Mode
0 = P31 as Demodulator Input
1 = P20 as Demodulator Input
Transmit/Demodulation Modes
0 = Transmit Mode *
1 = Demodulation Mode
1 T16_OUT is 1 initially
Note: Care must be taken in differentiating
transmit mode from demodulation mode.
Depending on which of these two modes is
operating, the CTR1 bit has different
functions.
Note: Changing from one mode to
another cannot be done without
disabling the counter/timers.
