#
Reset processor. RESET# low resets the processor to the
initial state and halts all activity. RESET# must be low for
at least one cycle. On a transition from low to high, a Reset
exception occurs and the processor starts execution at the
Reset entry determined by the INT4 state. The transition
may occur asynchronously to the clock. We recommend
connecting this pin to a voltage monitoring circuit with
open-drain output (e.g. Torex XC61A) supplying a reset
signal for supply voltages less than 2.6 or 2.7V, connected
to a R/C combination of 100 kΩ and 100 nF giving an
additional reset delay in the order of 10 ms.

XTALR
R/C Clock Oscillator Resistor Output. The resistor
connected between this pin and XTALI determines the
operating clock frequency. Use a 470Ω resistor to obtain a
frequency of about 20 MHz
