I/O Pin Name Description
Power Vcc
supply
Input
Power Supply Power supply for the internal logic of this LSI. All the Vcc
pins must be connected to the system power supply. This
LSI does not operate correctly if there is a pin left open.
Vss
Input Ground
Ground pins. All the Vss pins must be connected to the
system power supply (0 V). This LSI does not operate
correctly if there is a pin left open.
VccQ
Input
Power Supply Power supply for input/output pins. All the VccQ pins must
be connected to the system power supply. This LSI does not
operate correctly if there is a pin left open.
VssQ
Input Ground
Ground pins. All the VssQ pins must be connected to the
system power supply (0 V). This LSI does not operate
correctly if there is a pin left open.
Clock
Vcc (PLL1) Input Power Supply Power supply pin for the on-chip PLL1 oscillator
for PLL1
Vss (PLL1) Input Ground for
PLL1
Ground pin for the on-chip PLL1 oscillator
Vcc (PLL2) Input Power Supply Power supply pin for the on-chip PLL2 oscillator
for PLL2
Vss (PLL2) Input Ground for
PLL2
Ground pin for the on-chip PLL2 oscillator
EXTAL
Input
External Clock Connects to a crystal resonator. An external clock is also
input on this pin. For details on connection of an external
clock, see section 8, Clock Pulse Generator (CPG).
XTAL
Output Crystal
Connects to a crystal resonator.
CKIO
Output System Clock Supplies the system clock to external devices.

RES
Input
Input
Mode Setting
Power-On
Reset
Sets operating mode. The signal levels of these pins must
not be changed during operation.
Pins MD2 to MD0 are used for setting clock mode, pin MD3
is for setting bus width mode for area 0, and pin MD5 is for
setting endian.
This LSI enters the reset state when this signal goes low.
