FAULTSTAT Status of PWM Output Signal
0 = Normal operating
1 = High-Z (Inverter motor block is operating but the status of PWM signal is High-Z.
This bit can be set by fault detection of PWMxOFF pin or IMCON0.14.)
Note: If this bit is written to 0 and IMCON0.14 is 0, inverter motor control signal is output to PWM output.
UPDOWNSTAT Status of PWM Counter
0 = Up counting Æ This bit is always ‘0’ in the saw-tooth mode.
1 = Down counting
