8.47 READ BANK ADDRESS REGISTER OPERATION (RDBR: 16h/C8h)

The Read Bank Address Register (RDBR) instruction allows the Bank Address Register contents to be read. RDBR

is used to read only a volatile Bank Address Register.

The instruction code is first shifted in. Then the 8-bit Bank Register is shifted out. It is possible to read the Bank

Address Register continuously by providing multiples of eight bits.

Data is shifted in from SI and data is shifted out from SO in SPI sequence whereas data in and out is via four pins

(IO0-IO3) in QPI sequence.
