Direction
Peripheral clock output. This signal is
derived internally from the main system
oscillator as perclk, and may be divided
by 8, doubled, or both, by programmable
internal circuitry. This signal is enabled
after reset. Under program control, this pin
can output the full internal clock frequency,
or 1/2 the internal frequency, or it can be
used as a general-purpose output pin under
software control. See Table 7-4, “Global
Output Control Register (GOCR = 0x0E).”
Master reset.
Quartz crystal for 32 kHz clock oscillator.
Lines to the crystal should be short and
shielded from crosstalk. If an external
clock is used, this pin should be driven by
the external clock.
Quartz crystal for 32 kHz crystal oscillator.
Do not connect if an external clock is used.
Quartz crystal for main system oscillator.
Lines to the crystal should be short and
shielded from crosstalk. If an external
clock is used this pin should be driven by
the external clock.
Quartz crystal for main system oscillator.
Do not connect if an external clock is used.
Address bus.
WDT timeout—outputs a pulse when the
internal watchdog times out. May also be
used to output a 30 µs pulse.
Programmable for functions:
acknowledge cycle
See Table 7-4, “Global Output Control
Register (GOCR = 0x0E).”.
1. driven low on first opcode fetch cycle
2. driven low during interrupt
3. to serve as a general-purpose output.
