8.5 Banks and registers
The device registers enable the microcontroller to control the TDA8026. These registers
are defined as banks:
Remark: The registers are organized in bank pages in order to keep compatibility with the
TDA8023.
Bank 1 page selection is performed when the configuration byte (CSb[7:0]) is written to
the high I

Bank 0 register is a read/write register which enables selection of the required card
slot number and access to the corresponding registers Bank 1 registers. In addition,
Bank 0 is used to write information about the interrupt status and the product version.
The registers in bank 0 (CSb[7:0] = 1h to 5h) are similar to the registers of the
TDA8023.
Bank 1 provides access to the corresponding card slot registers. Bank 1 is composed
of several pages which in turn contain registers related to each individual card slot or
general registers. Typically, pages can contain two general registers or five card slot
related registers.
