Name and Function
Ground pin for on-chip PLL oscillator
External capacitance pin for on-chip PLL
oscillator
Connects to a crystal oscillator.
See section 20, Clock Pulse Generator,
for typical connection diagrams for a
crystal oscillator.
The EXTAL pin can also input an
external clock.
Connects to a 32.768-MHz crystal
oscillator. See section 20, Clock Pulse
Generator, for typical connection
diagrams for a crystal oscillator.
Supplies the system clock to an external
device.
These pins set the operating mode.
These pins should not be changed while
this LSI is operating.
Reset pin
When this pin is driven low, the chip is
reset.
When this pin is driven low, a transition
is made to hardware standby mode.
Pin for flash memory
Requests a nonmaskable interrupt.
When this pin is not used, it should be
fixed high.
These pins request a maskable
interrupt.
These pins output an address.
These pins constitute a bidirectional
data bus.
