Figure 35-17. Typical dual full H-bridge mode configuration
16-bit write accesses to the duty cycle registers are allowed, 8-bit write accesses can lead to unpredictable
duty cycles.
The following sequence should be used to update the current magnitude and direction for coil 0 and coil 1
of the motor to achieve consistent PWM output:
1. Write to duty cycle register x
2. Write to duty cycle register x + 1
At the next timer counter overflow, the duty cycle registers will be copied to the working duty cycle
registers. Sequential writes to the duty cycle register x will result in the previous data being overwritten.
35.4.1.1.2
Full H-bridge mode
In full H-bridge mode (
[MCOM]=0x2), the PWM channels x and x + 1 operate independently.
The duty cycle working registers are updated whenever a timer counter overflow occurs.
35.4.1.1.3
Half H-bridge mode
In half H-bridge mode (
[MCOM] = 0x0 or 0x1), the PWM channels x and x + 1 operate
independently. In this mode, each PWM channel can be configured such that one pin is released and the
other pin is a PWM output.
shows a typical configuration in half H-bridge mode.
The two pins associated with each channel are switchable between released mode and PWM output
dependent upon the state of the output mode bits
[MCOM]. See register description in
