supply
AGND
I
Analog GND pin
XT0
I
Sub clock oscillation input pin
Connect to a crystal oscillator of f = 32.768 kHz.
XT1
O
Sub clock oscillation output pin
Connect to a crystal oscillator of f = 32.768 kHz.
The clock output is opposite in phase to XT0.
OSC0
I
Main clock oscillation input pin
Connect to a crystal or ceramic oscillator. Or, input an external
clock.
Oscillation
OSC1
O
Main clock oscillation output pin
Connect to a crystal or ceramic oscillator.
The clock output is opposite in phase to OSC0.
Leave this pin unconnected when an external clock is used.
Reset
RES
I
Reset input pin
NMI
I
Non-maskable interrupt input pin
EA
I
External program memory access input pin
If the EA pin is enabled (low level), the internal program memory is
masked and the CPU executes the program code in external
program memory through all address space.
Other
SELMBUS
I
SELMBUS = H: Address/data separate bus type
SELMBUS = L: Multiplexed bus type
* Each of the family devices has unique pattern routes for the internal power and ground. Connect the
power supply voltage to all VDD pins and the ground potential to all GND pins. If a device may have one
or more VDD or GND pins to which the power supply voltage or the ground potential is not connected, it
can not be guaranteed for normal operation.
