OSCILLATOR CHARACTERISTICS
XTAL1 and XTAL2 are the input and output, respectively, of an
inverting amplifier. The pins can be configured for use as an
on-chip oscillator.
To drive the device from an external clock source, XTAL1 should be
driven while XTAL2 is left unconnected. Minimum and maximum
high and low times specified in the data sheet must be observed.
RESET
A reset is accomplished by holding the RST pin high for at least two
machine cycles (12 oscillator periods), while the oscillator is running.
To insure a good power-on reset, the RST pin must be high long
enough to allow the oscillator time to start up (normally a few
milliseconds) plus two machine cycles. At power-on, the voltage on
V
CC
and RST must come up at the same time for a proper start-up.
Ports 1, 2, and 3 will asynchronously be driven to their reset
condition when a voltage above V
IH1
(min.) is applied to RESET.
The value on the EA pin is latched when RST is deasserted and has
no further effect.
