Stand-by voltage supply to static RAM. Used to maintain the contents of
RAM with minimal power when the rest of the chip is powered down.
These pins provide the interface for either a crystal or a CMOS
compatible clock to control the internal clock generator circuitry. Out of
reset the frequency applied to EXTAL is twice the desired E–clock rate.
All the device clocks are derived from the EXTAL input frequency.
