PTSCON

Address: PTSPCB + 1

The PTS control (PTSCON) register selects the PTS mode and sets up control functions for that mode.

		These bits select the PTS mode:
		M2	M1	M0
		0	0	0	block transfer
		0	0	1	reserved
		0	1	0	PWM toggle or remap
		0	1	1	reserved
		1	0	0	single transfer

		1	1	0	reserved
		1	1	1	reserved

†The function of this bit depends upon which mode is selected. See the PTS control block description in each PTS mode section.

6.6.3Single Transfer Mode

In single transfer mode, an interrupt causes the PTS to transfer a single byte or word (selected by the BW bit in PTSCON) from one memory location to another. This mode is typically used with serial I/O or synchronous serial I/O interrupts. It can also be used with the EPA to move captured time values from the event-time register to internal RAM for further processing. See AP-445, 8XC196KR Peripherals: A User’s Point of View, for application examples with code. Figure 6-12 shows the PTS control block for single transfer mode.
