Chapter 11 Motor Controller (MC10B12CV2) Block Description
11.1.2.2 PWM Channel Configuration Modes
The twelve PWM channels can operate in three functional modes. Those modes are, with some
restrictions, selectable for each channel independently.
11.1.2.2.1 Dual Full H-Bridge Mode
This mode is suitable to drive a stepper motor or a 360o air gauge instrument. For details, please refer to
Section 11.4.1.1.1, “Dual Full H-Bridge Mode (MCOM = 11)”. In this mode two adjacent PWM channels
are combined, and two PWM channels drive four pins.
11.1.2.2.2 Full H-Bridge Mode
This mode is suitable to drive any load requiring a PWM signal in a H-bridge configuration using two pins.
For details please refer to Section 11.4.1.1.2, “Full H-Bridge Mode (MCOM = 10)”.
11.1.2.2.3 Half H-Bridge Mode
This mode is suitable to drive a 90o instrument driven by one pin. For details, please refer to
Section 11.4.1.1.3, “Half H-Bridge Mode (MCOM = 00 or 01)”.
11.1.2.3 PWM Alignment Modes
Each PWM channel can operate independently in three different alignment modes. For details, please refer
to Section 11.4.1.3.1, “PWM Alignment Modes”.
11.1.2.4 Low-Power Modes
The behavior of the motor controller in low-power modes is programmable. For details, please refer to
Section 11.4.5, “Operation in Wait Mode” and Section 11.4.6, “Operation in Stop and Pseudo-Stop
Modes”.
