For normal operation, it should not be connected . RESET: Reset the MCU. XIN: Input to the inverting oscillator amplifier and input to the internal main clock operating circuit. XOUT: Output from the inverting oscillator amplifier. OSC1: Input to the internal On Screen Display operating circuit. OSC2: Output from the inverting OSC1 amplifier. R00~R07: R0 is an 8-bit CMOS bidirectional I/O port. R0 pins 1 or 0 written to the Port Direction Register can be used as outputs or inputs. R10~R17: R1 is an 8-bit CMOS bidirectional I/O port. R1 pins 1 or 0 written to the Port Direction Register can be used as outputs or inputs. In addition, R1 serves the functions of the various follow- ing special features. R20~R27: R2 is a 8-bit CMOS bidirectional I/O port. Each pins 1 or 0 written to the their Port Direction Register can be used as outputs or inputs. In addition, R2 serves the functions of the various follow- ing special features. R40~R47: R40~R43 are 8-bit NMOS open drain output and R45~R47 are bidirectional CMOS Input / NMOS open drain output port. R4 pins 1 or 0 written to the Port Direc- tion Register can be used as outputs or inputs. In addition, R4 serves the functions of the various follow- ing special features. R50~R56: R50~R53 are 4-bit CMOS bidirectional I/O and R54~R56 are CMOS output port. R5 pins 1 or 0 written to the Port Direction Register can be used as outputs or in- puts. In addition, R5 serves the functions of the various follow- ing special features. R67: R67 is an 1-bit CMOS bidirectional I/O port. R67 pins 1 or 0 written to the Port Direction Register can be used as outputs or inputs. In addition, R67 serves the functions of the various follow- ing special features.
