Function
Stepper Motor Controller/Driver control
This bit switches both Stepper Motor Controller/Driver 0 and Stepper Motor
Controller/Driver 1.
Sets the count range of the timer counter
The initial start value is 00
and PWM cycle time, see also “Duty Factor“ on page 804.
Timer operation control
Sets the timer count clock for the timer counter
. This register is cleared by any reset.
0: Stepper Motor Controller/Driver operation is disabled.
1: Stepper Motor Controller/Driver operation is enabled.
0: count range from 01
1: count range from 00
0: Timer counteris stopped.
1: Timer counter is enabled.
