Chapter 9 Motor Controller (MC10B8CV1)
9.4.1.2
The pair of motor controller channels cannot be placed into dual full H-bridge mode unless both motor
controller channels have been enabled (MCAM[1:0] not equal to 00) and dual full H-bridge mode is
selected for both PWM channels (MCOM[1:0] = 11). If only one channel is set to dual full H-bridge mode,
this channel will operate in full H-bridge mode, the other as programmed.
9.4.1.3
9.4.1.3.1
Each PWM channel can be programmed individually to three different alignment modes. The mode is
determined by the MCAM[1:0] bits in the corresponding channel control register.
Left aligned (MCAM[1:0] = 01): The output will start active (low if RECIRC = 0 or high if RECIRC = 1)
and will turn inactive (high if RECIRC = 0 or low if RECIRC = 1) after the number of counts specified by
the corresponding duty cycle register.
