6.7.19 CT16Bn PWM Enable register (CT16Bn_PWMENB) (n=1)

Address Offset: 0x9C

The PWM Control register is used to configure the match outputs as PWM outputs. Each match output can be
independently set to perform either as PWM output or as match output whose function is controlled by

register.
For each timer, a maximum of 4 single edge controlled PWM outputs can be selected on the CT16Bn_PWMCTRL[3:0]
outputs. One additional match register determines the PWM cycle length. When a match occurs in any of the other
match registers, the PWM output is set to HIGH. The timer is reset by the match register that is configured to set the
PWM cycle length. When the timer is reset to zero, all currently HIGH match outputs configured as PWM outputs are
cleared.
