INTERNAL REGISTERS

The addresses associated with the internal registers

are listed below. A detailed description of the registers

follows. All registers are 8-bit long and can be

addressed separately. READ modes define the groups

and

types

registers

for

continuous

read

communication or looping on address sets.
