PTSSRV	Address:	0006H
	Reset State:	0000H

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.

Function

14:0†

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.
