Motor Controller (MC10B8CV1)
20.2 External Signal Description
The motor controller is associated with 16 pins. Table 20-2 lists the relationship between the PWM
channels and signal pins as well as PWM channel pair (motor number), coils, and nodes they are supposed
to drive if all channels are set to dual full H-bridge configuration.

1 _{A PWM Channel Pair always consists of PWM channel x and PWM channel x+1 (x = 2⋅n). The term}
“PWM Channel Pair” is equivalent to the term “Motor”. E.g. Channel Pair 0 is equivalent to Motor 0
20.2.1 M0C0M/M0C0P/M0C1M/M0C1P — PWM Output Pins for Motor 0
High current PWM output pins that can be used for motor drive. These pins interface to the coils of
motor 0. PWM output on M0C0M results in a positive current flow through coil 0 when M0C0P is driven
to a logic high state. PWM output on M0C1M results in a positive current flow through coil 1 when
M0C1P is driven to a logic high state.
20.2.2 M1C0M/M1C0P/M1C1M/M1C1P — PWM Output Pins for Motor 1
High current PWM output pins that can be used for motor drive. These pins interface to the coils of
motor 1. PWM output on M1C0M results in a positive current flow through coil 0 when M1C0P is driven
to a logic high state. PWM output on M1C1M results in a positive current flow through coil 1 when
M1C1P is driven to a logic high state.
20.2.3 M2C0M/M2C0P/M2C1M/M2C1P — PWM Output Pins for Motor 2
High current PWM output pins that can be used for motor drive. These pins interface to the coils of
motor 2. PWM output on M2C0M results in a positive current flow through coil 0 when M2C0P is driven
