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).

Register Location Function
PTSCONST1 PTSCB + 4 PWM Const 1 Value
Write the desired PWM on-time to these bits.
PTSPTR1 PTSCB + 2 Pointer 1 Value
These bits point to a memory location, usually EPA
x
_TIME. PTSPTR1
can point to any unreserved memory location within page 00H.
