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
Value Description
1 Any queued update to a load or comparator register in PWM
generator 3 is applied the next time the corresponding counter
becomes zero.
0 No effect.
This bit automatically clears when the updates have completed; it cannot
be cleared by software.
Update PWM Generator 2
Value Description
1 Any queued update to a load or comparator register in PWM
generator 2 is applied the next time the corresponding counter
becomes zero.
0 No effect.
This bit automatically clears when the updates have completed; it cannot
be cleared by software.
Update PWM Generator 1
Value Description
1 Any queued update to a load or comparator register in PWM
generator 1 is applied the next time the corresponding counter
becomes zero.
0 No effect.
This bit automatically clears when the updates have completed; it cannot
