OTP ROM

0 = Calibration disable;

1 = Calibration enable.

Bit 6 (SIGN2): Polarity bit of offset voltage

0= Negative voltage;

1= Positive voltage.

Bit 5:Bit 3 (VOF2[2]:VOF2[0]): Offset voltage bits

Bit 1:Bit 0 (PWM2[9]:PWM2[8]): The Most Significant Byte of PWM1 Duty Cycle

A specified value keeps the PWM2 output to stay at high until the value matches with TMR2.
