Motor Controller (MC10B8CV1)
20.1.2.1.2 Dither Function
Dither function can be selected or deselected by setting or clearing the DITH bit. This bit influences all
PWM channels. For details, please refer to Section 20.4.1.3.5, âDither Bit (DITH)â.
20.1.2.2 PWM Channel Conï¬guration Modes
The eight PWM channels can operate in three functional modes. Those modes are, with some restrictions,
selectable for each channel independently.
20.1.2.2.1 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 20.4.1.1.1, âDual Full H-Bridge Mode (MCOM = 11)â. In this mode two adjacent PWM channels
are combined, and two PWM channels drive four pins.
20.1.2.2.2 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 20.4.1.1.2, âFull H-Bridge Mode (MCOM = 10)â.
20.1.2.2.3 Half H-Bridge Mode
This mode is suitable to drive a 90o instrument driven by one pin. For details, please refer to
Section 20.4.1.1.3, âHalf H-Bridge Mode (MCOM = 00 or 01)â.
20.1.2.3 PWM Alignment Modes
Each PWM channel can operate independently in three different alignment modes. For details, please refer
to Section 20.4.1.3.1, âPWM Alignment Modesâ.
20.1.2.4 Low-Power Modes
The behavior of the motor controller in low-power modes is programmable. For details, please refer to
Section 20.4.5, âOperation in Wait Modeâ and Section 20.4.6, âOperation in Stop and Pseudo-Stop
Modesâ.
