I
External Access Enable/Programming Supply Voltage:
EA must be externally held LOW to
enable the device to fetch code from external program memory. The value on the EA pin is
latched when RST is released and any subsequent changes have no effect.
XTAL1

I
Crystal 1:
Input to the inverting oscillator amplifier and input to the internal clock generator
circuits.
XTAL2
20
14
O
Crystal 2:
Output from the inverting oscillator amplifier.
NOTES:
1. To avoid “latch-up” effect at power-on, the voltage on any pin (other than EA) at any time must not be higher than V
CC
+ 0.5 V or less than
V
SS
– 0.5 V, respectively.
2. The pins are designed for test mode also.
