P = ESM functional clock

(2)

R = Error Pin Counter Pre-Load Register count value

(3)

H = Error Pin PWM High Pre-Load Register count value

(4)

L = Error Pin PWM Low Pre-Load Register count value

(5)

When PWM mode is enabled, SAFETY_ERRORn stops toggling after RST22 and will maintain its value (either high or low) until the

error is cleared. When PWM mode is disabled, SAFETY_ERRORn is active low
