7.0 INTERNAL REGISTERS

The addresses associated with the internal registers

are listed below, followed by a detailed description of

the registers. All registers are split in 8-bit long registers

which can be addressed and read separately. Read

and Write modes define the groups and types of

registers for continuous read/write communication or

looping on address sets as shown in Table 7-2.
