Description
TRANSMIT Mode
T8/T16 Logic—Defines how the Timer 8/Timer 16 outputs are combined logically.
These bits are not reset upon Stop Mode Recovery.
Output is T8 AND T16.
Output is T8 OR T16.
Output is T8 NOR T16.
Output is T8 NAND T16.
DEMODULATION Mode
Edge Detect—Define the behavior of the edge detector.
Falling edge detection.
Rising edge detection.
Falling and rising edge detection.
Reserved.
TRANSMIT Mode
Submode Selection—Select NORMAL or PING-PONG mode operation, or force
T16 output. When these bits are written to 00b (NORMAL mode) or 01b
(PING-PONG mode), T16_OUT assumes the opposite state of bit CTR1[0] until
the timer begins counting.
Normal operation. Writing 00 terminates PING-PONG mode, if it is active.
PING-PONG mode.
Force T16_OUT = 0
Force T16_OUT = 1
DEMODULATION Mode
Glitch Filter—Define the maximum glitch width to be rejected by the
counter/timer.
No filter.
4 SCLK cycle filter.
8 SCLK cycle filter.
Reserved.
