52 / 81 page  Rev. 1.30 54 May 17, 2022 Rev. 1.30 55 May 17, 2022 HT45F0057 Induction Cooker Flash MCU HT45F0057 Induction Cooker Flash MCU CPnN CnVO - + S1 S2 S3 - + CnVO Vr CPnP Comparator (n=0~3) Comparator registers Full control over the internal comparator is provided via the control registers, CMP0C, CMP1C, CMP2C, CMP3C, and CMPSC. These registers are used to select the input path and the offset voltage cancellation function.
