Power supply
Power supply for chip-internal and
system ports (RES, MD2–MD0, FWE,
HSTBY, NMI, CK, EXTAL, XTAL, H-UDI
port). Connect all V_CC pins to the system
power supply. The chip will not operate if
there are any open pins.

supply 1
Power supply for bus ports (ports E, F,
and H). Connect all PV_CC1 pins to the
system bus power supply. The chip will
not operate if there are any open pins.

supply 2
Power supply for peripheral module ports
(ports A, B, C, D, G, J, K, and L, the AUD
port, and WDTOVF). Connect all PV_CC2
pins to the system peripheral module
power supply. The chip will not operate if
there are any open pins.

Input
Internal step-
down power
supply
Pins for connection to a capacitor used
for stablizing the voltage of the internal
step-down power supply.
Connect V_SS to this pin through a
(0.33,0.47)-μF capacitor. The capacitor
should be located near the pin. Do not
connect an external power supply to the
pin.
