C. Time Compare Outputs
Outputs a pulse at the programmed compare time #1.
Outputs a pulse at the programmed compare time #2.
Asserts the Interval level during the interval between compare time #1 and
compare time #2.
Resolution - 1 microsecond
Pulse Width - 2 milliseconds
Compare Mask - milliseconds through hundreds of days
Signal Level - Positive going, +5v @ +/- 6ma
See section 1.6.4 for P2/J2 pin assignment
