The PENH and PENL bits in the IOCONx register
are used to assign ownership of the pins to either
the PWM module or the GPIO module. The correct
procedure to configure the PWM module is to first
assign pin ownership to the PWM module and then
enabling it using the PTEN bit in the PTCON
register.
If the PWM module is enabled using the above
sequence, then a glitch may be observed on the
PWM pins before actual switching of the PWM
outputs begins. This glitch may cause momentary
turn ON of power MOSFETs that are driven by the
PWM pins and may cause damage to the
application hardware.
Work around
Follow the given sequence to avoid any glitches
from appearing on the PWM outputs at the time of
enabling.

put the PWM pins in a high-impedance state.
The PWM outputs must be maintained in a safe
state by using pull-up or pull-down resistors.
