Note: When the match outputs are selected to serve as PWM outputs, the timer reset
(MRnR) and timer stop (MRnS) bits in the Match Control Register MCR must be set to 0
except for the match register setting the PWM cycle length. For this register, set the
MRnR bit to 1 to enable the timer reset when the timer value matches the value of the
corresponding match register.

Description
When one, PWM mode is enabled for CT16Bn_MAT0.
When zero, CT16Bn_MAT0 is controlled by EM0.
When one, PWM mode is enabled for CT16Bn_MAT1.
When zero, CT16Bn_MAT1 is controlled by EM1.
When one, PWM mode is enabled for match channel 2
or pin CT16B0_MAT2. When zero, match channel 2 or
pin CT16B0_MAT2 is controlled by EM2. Match channel
2 is not pinned out on timer 1.
When one, PWM mode is enabled for match channel
3match channel 3. When zero, match channel 3 is
controlled by EM3. Match channel 3 is not pinned out on
timer 1.
Note: It is recommended to use this channel match
channel 3 to set the PWM cycle because it is not pinned
out.
Reserved, user software should not write ones to
reserved bits. The value read from a reserved bit is not
defined.
