Read the PWM period counter value.
PWM period MDPRD ≥ 010H.
Set U-phase PWM duty cycle.
Set V-phase PWM duty cycle.
Set W-phase PWM duty cycle.
Code input for disable EMG protection circuit.
Can be disable by writing 5AH and then A5H.
Return from overload protective state.
0: No operation
1: Return from protective state
Condition for returning from overload protective state:
Synchronized to PWM.
0: Disable
1: Enable
Enable/Disable return from overload protective state by timer 1.
0: Disable
1: Enable
Overload protective state.
0: No operation
1: Under protection
Select output disabled phases during overload protection.
00: No phases disabled against output
01: All phases disabled against output
10: PWM phases disabled against output
11: All upper/All lower phases disabled against output
Stop PWM counter (MDCNT) during overload protection.
0: Do not stop
1: Stop
Enable/Disable overload protective circuit.
0: Disable
1: Enable
Overload protection sampling time.

EMG protective state.
0: No operation
1: Under protection
Return from EMG protective state.
0: No operation
1: Return from protective state
Enable/Disable fanction of the EMG protective circuit.
0: Disable
1: Enable
(This circuit initially is enabled (= 1). To disable this circuit, make sure
key code 5AH and A5H are written to the EMGREL1 Register before-
hand.)
