9.1.2.2 PWM Channel Configuration Modes
The eight PWM channels can operate in three functional modes. Those modes are, with some restrictions,
selectable for each channel independently.
9.1.2.2.1 Dual Full H-Bridge Mode
This mode is suitable to drive a stepper motor or a 360^o air gauge instrument. For details, please refer to
Section 9.4.1.1.1, “Dual Full H-Bridge Mode (MCOM = 11)”. In this mode two adjacent PWM channels
are combined, and two PWM channels drive four pins.
9.1.2.2.2 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 9.4.1.1.2, “Full H-Bridge Mode (MCOM = 10)”.
9.1.2.2.3 Half H-Bridge Mode
This mode is suitable to drive a 90^o instrument driven by one pin. For details, please refer to
Section 9.4.1.1.3, “Half H-Bridge Mode (MCOM = 00 or 01)”.
9.1.2.3 PWM Alignment Modes
Each PWM channel can operate independently in three different alignment modes. For details, please refer
to Section 9.4.1.3.1, “PWM Alignment Modes”.
9.1.2.4 Low-Power Modes
The behavior of the motor controller in low-power modes is programmable. For details, please refer to
Section 9.4.5, “Operation in Wait Mode” and Section 9.4.6, “Operation in Stop and Pseudo-Stop Modes”.
