T16 TRANSMIT Mode
In NORMAL or PING-PONG mode, the output of T16 when not enabled, is dependent on
CTR1, D0. If it is a 0, T16_OUT is a 1; if it is a 1, T16_OUT is 0. You can force the output
of T16 to either a 0 or 1 whether it is enabled or not by programming CTR1 D3; D2 to a 10
or 11.
When T16 is enabled, TC16H * 256 + TC16L is loaded, and T16_OUT is switched to its
initial value (CTR1, D0). When T16 counts down to 0, T16_OUT is toggled (in
NORMAL or PING-PONG mode), an interrupt (CTR2, D1) is generated (if enabled), and
a status bit (CTR2, D5) is set. See
Global interrupts override this function as described in
If T16 is in SINGLE-PASS mode, it is stopped at this point (see
MODULO-N mode, it is loaded with TC16H * 256 + TC16L, and the counting continues
(see
You can modify the values in TC16H and TC16L at any time. The new values take effect
when they are loaded.
