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. Since the P89C668 has 64k internal
memory, the P89C668 will execute only from internal memory when EA is held high. This pin also
receives the programming supply voltage (V
PP
) during Flash programming.

Crystal 2:
Output from the inverting oscillator amplifier.
NOTE:
To avoid “latch-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.
