Supply 2.7V(Note1) to 5.5 V to the VCC pin. Supply 0 V to the VSS pin.
Connect a bypass capacitor across the VCC pin and VSS pin.
Function
Connect it to the VSS pin.
A “L” on this input resets the microcomputer.
These pins are provided for the main clock generating circuit.Connect
a ceramic resonator or crystal between the XIN and the XOUT pins. To
use an externally derived clock, input it to the XIN pin and leave the
XOUT pin open.
This pin is a power supply input for the A-D converter. Connect this
pin to VCC.
This pin is a power supply input for the A-D converter. Connect this
pin to VSS.
This is an 8-bit CMOS output port and high-breakdown-voltage P-
channel open-drain output structure. A pull-down resistor is built in
between port P0 and VEE pin. At reset, this port is set to VEE level. P0
function as FLD controller output pins as selected by software.
This is an 8-bit output port equivalent to P0. Pins in this port also
function as FLD controller output pins as selected by software.
This is an 8-bit output port equivalent to P0. A pull-down resistor is not
built in between P2 and VEE pin. Pins in this port also function as FLD
controller output pins as selected by software.
This is an 8-bit I/O port. A pull-down resistor is not built in between P3
and VEE pin. It has an input/output port direction register that allows the
user to set each pin for input or output. This is low-voltage input level,
and high-breakdown-voltage P-channel open-drain output structure.
Pins in this port also function as FLD controller output pins as selected
by software.
This is an 8-bit I/O port equivalent to P3. This is low-voltage input level.
P40 to P43 is high-breakdown-voltage P-channel open-drain output
structure, P44 to P47 is CMOS output. A pull-down resistor is not built
in between P4(P40 to P43) and VEE pin. Pins in this port also function
as FLD controller output pins as selected by software. P44 to P47 also
function as UART0 I/O pins as selected by software. When set for
input, the user can specify in units of four bits by software whether or
not they are tied to a pull-up resistor.
