8XC196NP, 80C196NU USER’S MANUAL

PTS PWM Remap Mode Control Block

In PWM remap mode, the PTS uses two EPA channels to generate a pulse-width modulated (PWM) output signal. The control block contains registers that contain the PWM on-time (PTSCONST1), the address pointer (PTSPTR1), and a control register (PTSCON).
