Byte Control Logic Operation
The AT43101 provides separate output and write enables for
the upper and lower bytes of the memory array to implement
byte addressing. The assertion of these outputs under the
control of A0, CE2*, CE1*, OE* and WE* is given by the
following table when REG* is high.
The IWP* input provides write protection for common
memory. When IWP* is low, assertion of IWEL* and
IWEH* is inhibited. The WPATT input provides write pro-
tection for the attribute memory when high. This signal is
pulled down internally for applications not requiring write
protection. In addition, the AT43101 is disabled for 3 milli-
seconds during power up to prevent writes from occurring
to either attribute or common memory. The state of the
A*/B pin is also latched at this time. The AT43101 does
not support the optional PCMCIA WAIT* signal.
