External Access Enable/Programming Supply Voltage:
EA must be externally held low to
enable the device to fetch code from external program memory locations. If EA is held high, the
device executes from internal program memory. The value on the EA pin is latched when RST
is released and any subsequent changes have no effect. This pin also receives the
programming supply voltage (V
PP
) during Flash programming.
Crystal 1:
Input to the inverting oscillator amplifier and input to the internal clock generator
circuits.

Crystal 2:
Output from the inverting oscillator amplifier.
NOTE:
To avoid “l(fā)atch-up” effect at power-on, the voltage on any pin (other than V
PP
) must not be higher than V
CC
+ 0.5 V or less than V
SS
– 0.5 V.
