Pulse Width Modulator (PWM)
Register 2: PWM Time Base Sync (PWMSYNC), offset 0x004
This register provides a method to perform synchronization of the counters in the PWM generation
blocks. Setting a bit in this register causes the specified counter to reset back to 0; setting multiple
bits resets multiple counters simultaneously. The bits auto-clear after the reset has occurred; reading
them back as zero indicates that the synchronization has completed.

Reset Description
RO 0x0000.000 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.
