5 REGISTERS
Five address bits are used to control the settings of the registers. AD[4:0] are used in both the parallel
nonmultiplexed mode and in multiplexed mode. In serial mode, the address is input serially on SDI. The register
space contains control for channels 1 to 8 from address 00 hex to 1F hex. The
pointer to access the different banks of registers. This register must be set to AA hex for access of the secondary
bank of registers, 01 hex for access to the individual LIU bank of registers, and 02 hex for access of the BERT
bank of registers. The primary bank of registers is accessed upon reset of this register to 00 hex.
