4 REGISTER MAP AND DESCRIPTIONS
4.1 OVERVIEW
The following section tabulates the register map of the CIO-QUAD series and briefly describes the commands necessary to
program the CIO-QUAD at the register level. The heart of the board is the LSI/CSI LS7266R1, a powerful device which is
highly integrated, requiring fewer external components. As seen in the LS7266R1 block diagram, many functions are
controlled through register programming. Refer to the register map in Table 4-1 below and the following descriptions.
