I
Power supply Power supply pins. 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.
I
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.
I
Power supply for Power supply for I/O pins. All the
I/O circuits
PVcc pins must be connected to the
system power supply. This LSI does
not operate correctly if there is a pin
left open.
I
Ground for I/O Ground pins for I/O pins. All the
circuits
PVss pins must be connected to the
system power supply (0 V). This LSI
does not operate correctly if there is
a pin left open.
I
Power supply for Power supply for the on-chip PLL
PLL
oscillator.
I
Ground for PLL Ground pin for the on-chip PLL
oscillator.
I
External clock Connected to a crystal resonator. An
external clock signal may also be
input to the EXTAL pin.
O Crystal
Connected to a crystal resonator.
I/O System clock I/O Inputs an external clock or supplies
the system clock to external devices.
