HMS9xC7132 / HMS9xC7134
5. PIN FUNCTION
VDD1: Supply voltage (Digital).
VSS1: Circuit ground (Digital).
VDD2: Supply voltage (Analog).
VSS2: Circuit ground (Analog).
RESET: Reset the MCU.
XTAL1: Input to the inverting oscillator amplifier and input to
the internal main clock operating circuit.
XTAL2: Output from the inverting oscillator amplifier.
HSYNCIN: Horizontal sync input
VSYNCIN: Vertical sync input
INT0/VPP: External Interrupt input. Programming supply volt-
age(during OTP programming)
PORT:
The HMS9xC7132 has four 8-bit ports (Port0, Port1, Port2,
and Port3). Port0 - Port3 are the same as in the 80C51, with
the exception of the additional functions of Port1, Port2 and
Port3. Each has latch, SFR P0~P3’ output driver and input
buffer.
P0.0~P0.7: P0 is an 8-bit CMOS bidirectional I/O port. P0 pins
have not pull-up resister and open-drain port. It has the capability
of drive LED. However, while the alternative function is per-
formed, the port type will remain the same. In case of application
to extention of external memory, P0 outputted Write/Read byte
and lower byte of external memory address. Therefore when it is
used as normal I/O port, P0 is open-drain driver and when it used
as bus port, P0 is 3-state driver.

P1.0~P1.7: P1 is an 8-bit CMOS bidirectional I/O port. Because
P1 pins have pull-up resister, it is called as Quasi-Bidirectional
port.
