External address latch enable. The local bus memory controller provides control for an external address
latch, which allows address and data to be multiplexed on the device pins.
Chip selects. Four chip selects are provided that are mutually exclusive.

ORn[EAD] and LCRR[EADC] fields. Note that no other control signals are asserted
during the assertion of LALE.
