3.13
EA/VPP
External Access Enable. EA must be strapped to GND in order to enable the device to fetch
code from external program memory locations starting at 0000H up to FFFFH. Note, however,
that if lock bit 1 is programmed, EA will be internally latched on reset.
EA should be strapped to V
CC for internal program executions. This pin also receives the 12-volt
programming enable voltage (V
PP) during Flash programming when 12-volt programming is
selected.
3.14
XTAL1
Input to the inverting oscillator amplifier and input to the internal clock operating circuit.
3.15
XTAL2
Output from the inverting oscillator amplifier. XTAL2 should not drive a board-level clock without
a buffer.
