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 corresponding
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 end-of-PTS interrupt service routine must set
the PTSSEL bit to re-enable the PTS channel.

A bit is set by hardware to request an end-of-PTS interrupt for the corresponding interrupt
through its standard interrupt vector.
The standard interrupt vector locations are as follows:

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

Bit 13 is reserved on the 8XC196Lx
devices and bits 6–8 are reserved on the 87C196LA and
83C196LD. For compatibility with future devices, write zeros to these bits.
