Caution:
T16 DEMODULATION Mode
You must program TC16L and TC16H to
(rising, falling, or both depending on CTR1 D5; D4) is detected, T16 captures HI16 and
LO16, reloads, and begins counting.
If D6 of CTR2 Is 0
When a subsequent edge (rising, falling, or both depending on CTR1, D5; D4) is detected
during counting, the current count in T16 is complemented and put into HI16 and LO16.
When data is captured, one of the edge detect status bits (CTR1, D1; D0) is set, and an
interrupt is generated if enabled (CTR2, D2). T16 is loaded with
This T16 mode is generally used to measure space time, the length of time between bursts
of carrier signal (marks).
Do not load these registers at the time the values are to be loaded into the counter/timer
to ensure known operation. An initial count of 1 is not allowed. An initial count of 0
causes T16 to count from 0 to
timeout condition.
