Detailed Description

Results of stealthChop amplitude regulator register (PWM_SCALE)

Read-only register showing actual PWM duty cycle and automatic regulation results.

Bit assignments per datasheet:

• Bits 7..0: PWM_SCALE_SUM - Actual PWM duty cycle (0-255)
• Bits 24..16: PWM_SCALE_AUTO - 9-bit signed offset added to calculated PWM duty cycle Result of automatic amplitude regulation based on current measurement (signed -255...+255)
