(1)

P = ESM functional clock period in ns.

(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, MCU_ERRORn stops toggling after ERR3 and will maintain its value (either high or low) until the error is

cleared. When PWM mode is disabled, MCU_ERRORn is active low.
