IMEN Inverter Motor Block Enable/Disable Control Bit
0 = Disable IMC Block Æ IMCNT is cleared to 0 automatically
1 = Enable IMC Block
IMMODE Inverter Motor Mode Selection Bit
0 = Tri-angular shape
1 = Saw-tooth shape
This bit can be changed only when IMCON.0 is 0 .
If this bit is set to ‘1’, comparison with ‘0’ is no effect (INT_ZEROx will not be occurred.)
WMODE Write Mode Selection of Compare Register
0 = Immediate write
1 = Synchronous write
Note: In the synchronous write, if IMCNT equals to 0 or TOPCMP, compare registers including
dead-time compare register which are written are updated simultaneously. Synchronous write is related
to NUMSKIP. For example, if NUMSKIP is 30, synchronous write happens only one time in every 30
times. ADC trigger signal is the same situation.
PWMSWAP Swapping of PWMxUx and PWMxDx
0 = No Swap
1 = Swap
Note: This bit can be changed only when IMCON.0 is 0.
