PSEN
Program Store Enable Output, active low.
PSEN
enables the external ROM onto the Port 0
address/data bus during fetch and MOVC operations.
PSEN
goes to a high impedance state during
reset with a weak pull-up.
XTAL1
Crystal 1. This is the crystal oscillator input. This pin may be driven by an external clock.
XTAL2
Crystal 2. This is the crystal oscillator output. It is the inversion of XTAL1.
