6.6.3 Single 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.

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