Bank Address Register
Related Commands: Bank Register Access (BRAC B9h), Write Register (WRR 01h), Bank Register Read
(BRRD 16h) and Bank Register Write (BRWR 17h).
The Bank Address register supplies additional high order bits of the main flash array byte boundary address
for legacy commands that supply only the low order 24 bits of address. The Bank Address is used as the high
bits of address (above A23) for all 3-byte address commands when EXTADD=0. The Bank Address is not
used when EXTADD = 1 and traditional 3-byte address commands are instead required to provide all four
bytes of address.
Extended Address (EXTADD) BAR[7]: EXTADD controls the address field size for legacy SPI commands. By
default (power up reset, hardware reset, and software reset), it is cleared to 0 for 3 bytes (24 bits) of address.
When set to 1, the legacy commands will require 4 bytes (32 bits) for the address field. This is a volatile bit.
