DESCRIPTION
9B
ADSP#
Input
Synchronous Address Status Processor: This active LOW input
interrupts any ongoing burst, causing a new external address to be
registered. A READ is performed using the new address,
independent of the byte write enables and ADSC#, but dependent
upon CE#, CE2 and CE2#. ADSP# is ignored if CE# is HIGH. Power-
down state is entered if CE2 is LOW or CE2# is HIGH.
8A
ADSC#
Input
Synchronous Address Status Controller: This active LOW input
interrupts any ongoing burst, causing a new external address to be
registered. A READ or WRITE is performed using the new address if
CE# is LOW. ADSC# is also used to place the chip into power-down
state when CE# is HIGH.
1R
MODE
Input
Mode: This input selects the burst sequence. A LOW on this input
(LB0#)
selects “l(fā)inear burst.” NC or HIGH on this input selects “interleaved
burst.” Do not alter input state while device is operating.
