11 / 110 page  HMS81C4x60 November 2001 Ver 1.1 9 5. PIN FUNCTION VDD: Supply voltage. VSS: Circuit ground. TEST: Used for shipping inspection of the IC. 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. R00~R07: R0 is an 8-bit bidirectional I/O port. R0 pins 1 or 0 written to the Port Direction Register can be used as outputs or inputs. R10~R14: R1 is a 5-bit read only port. R1 pins 1 or 0 writ- ten to the Port Direction Register can be used as inputs. In addition, R1 serves the functions of the various follow- ing special features. R20~R25: R2 is a 6-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. R30~R37: R3 is 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. In addition, R3 serves the functions of the various follow- ing special features. R40~R43: R4 is a 4-bit open drain I/O port. Each pins 1 or 0 written to the their Port Direction Register can be used as outputs or inputs. In addition, R4 serves the functions of the various follow- ing special features. R,G,B: R,G,B are output port. Each pins controls Red, Green, Blue color control. YM,YS: YM,YS are CMOS output port. Each pins con- trols Background, Edge control. HS,VS: HS,VS are CMOS input port. Each pins Vertical Sync. input and Horizaltal Sync. inputs. CVBS: CVBS is a CVBS(Composit Video in) signal input pin.
