Bit 3 – FIFTY Fifty Percent Waveform
If the two waveforms have identical characteristics, this bit can be written to ‘1’. This will cause any values written to register TCDn.CMPBSET/TCDn.CLR also to be written to the register TCDn.CMPASET/TCDn.CLR.
Bit 1 – AUPDATE Automatically Update
If this bit is written to ‘1’ a synchronization at the end of the TCD cycle is automatically requested after the Compare B Clear High register (TCDn.CMPBCLRH) is written.
If the fifty percent waveform is enabled by setting the FIFTY bit in this register, writing the Compare A Clear High register will also request a synchronization at the end of the TCD cycle if the AUPDATE bit is set.
Bit 0 – CMPOVR Compare Output Value Override
When this bit is written to ‘1’, default values of the Waveform Outputs A and B are overridden by the values written in the Compare x Value in active state bit fields in the Control D register (CMPnxVAL bit in TCDn.CTRLD.). See the Control D register description for more details.
