Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Update PWM Generator 3
Same as GlobalSync0 but for PWM generator 3.
Update PWM Generator 2
Same as GlobalSync0 but for PWM generator 2.
Update PWM Generator 1
Same as GlobalSync0 but for PWM generator 1.
Update PWM Generator 0
Setting this bit causes any queued update to a load or comparator
register in PWM generator 0 to be applied the next time the
corresponding counter becomes zero. This bit automatically clears when
the updates have completed; it cannot be cleared by software.
