4.5
RST
Reset input. Holding the RST pin high for two machine cycles while the is running resets the
device.
Each machine cycle takes 6 or clock cycles.
4.6
XTAL1
Input to the inverting amplifier and input to the internal clock operating circuit.
4.7
XTAL2
Output from the inverting amplifier.
5.
Characteristics
XTAL1 and XTAL2 are the input and output, respectively, of an inverting amplifier which can be
configured for use as an on-chip , as shown in Figure 5-1. Either a quartz crystal or ceramic res-
onator may be used. To drive the device from an external clock source, XTAL2 should be left
unconnected while XTAL1 is driven as shown in Figure 5-2. There are no requirements on the
duty cycle of the external clock signal, since the input to the internal clocking circuitry is through
a divide-by-two flip-flop, but minimum and maximum voltage high and low time specifications
must be observed.
