PTSCOUNT
PTSCB1 + 0
Consecutive PTS Cycles
Defines the number of bits to be transmitted or received,
including parity and stop bits, but not the start bit. For
asynchronous modes, program a number that is between 1–16.
For synchronous modes, program a number that is twice the
number of bits to be transmitted or received (2–32). PTSCOUNT
is decremented at the end of each PTS cycle. When it reaches
zero, hardware clears the corresponding PTSSEL bit and sets
the PTSSRV bit, which requests the end-of-PTS interrupt.
