3. Pin Function
PIN Name Input/Output Function
Timer/Counter 2 input
Programmsble pulse generator output
Divider output
External interrupt input 2 or Timer/Counter 1 input
External interrupt input 1
External interrupt input 0
Resonator connecting pins(32.8kHz). For inputting
external clock,XTIN is used and XTOUT is opeded.
External interrupt input 5 or STOP mode retease signal input
Test pin for out-going test. Be tied to low.
+5V,0V(GND)
Be tied to low.
Resonator connecting pins for high-frequency clock.
For inputting external clock. XIN is used and XOUT is opend.
Reset signal input or watchdog timer output/address-trap-reset output/system-
clock-reset output.
– 20 –
Two 8-bit programmable input/output ports
(tri-state).
Each bit of these ports can be individually
configured as an input or an output under
software control.
During reset,all bits are configured as in-
puts.
When used as a divider output or a PPG
output, the latch must be set to “1”.
3-bit input/output port with latch.
When used as an input port,the latch must
be set to “1”.
2-bit output port with latch.
8-bit programmable input/output port (tri-
state).
When used as an input port, a SIO input/
output on external interrupt input or a
PWM/PDO output, the latch must be set
to “1”.
HSO serial data output
HSO serial clock output
SIO serial data output
SIO serial data input
SIO serial clock input/output
8-bit PWM output or 8-bit programmable divider output
External interrupt input 4
External interrupt input 3 or Timer/Counter 3 input
8-bit programmable input/output port (tri-
state). Each bit of the port can be indi-
vidually configured as an input or an out-
put under software control.
