The PTS service (PTSSRV) register is used by the hardware to indicate that the final PTS interrupt has
been serviced by the PTS routine. When PTSCOUNT reaches zero, hardware clears the corre-
sponding PTSSEL bit and sets the PTSSRV bit, which requests the end-of-PTS interrupt. When the
end-of-PTS interrupt is called, hardware clears the PTSSRV bit. The PTSSEL bit must be set manually
to re-enable the PTS channel.

PTS service is not useful for multiplexed interrupts because the PTS cannot readily
determine the source of these interrupts.
