pwm_min_pulse_width

R/W

Minimum output PWM pulse width allowed. Applies to all PWM

outputs.

00 = Minimum PWM pulse width = 1 clk period (100 ns, default)

01 = Minimum PWM pulse width = 2 clk periods (200 ns)

10 = Minimum PWM pulse width = 3 clk periods (300 ns)

11 = Minimum PWM pulse width = 4 clk periods (400 ns)

5–4

RESERVED

R/W

pwm_input_edge_sel

R/W

PWM input period measurement select.

0h = PWM period is measured from rising edge to rising edge.

(default)

1h = PWM period is measured from falling edge to falling edge.

2–0

pwm_input_hysteresis

R/W

PWM input hysteresis select

0h = No hysteresis

1h = 1 LSB

2h = 2 LSBs

3h = 3 LSBs

4h = 4 LSBs (default)

5h = 5 LSBs

6h = 6 LSBs

7h = 7 LSBs
