INTERNAL READ ACCESS
A read is performed by first writing the CAR and AMR as with
a write. The data registers (DR2–DR0) are then read in the
reverse order that they were written. First, the Least Significant
Byte of the data (D[7:0]) is read from DR0. On this transaction
the high bytes of the data are moved from the internal address
pointed to by the CAR and AMR into the remaining data registers
(DR2–DR1). This data can then be read from the data registers
using the appropriate 3-bit addresses. The number of data registers
used depends solely on the amount of data to be read or written.
Any unused bit in a data register should be masked out for a read.
Read Pseudocode
int read_micro(ext_address);

This code shows the reading of the first RCF coefficient
using the read_micro function as defined above. The variable
address is the External Address A[2..0].
Internal Address = 0x000

read D[7:0] from DR0. All data is moved from the Internal
Registers to the interface registers on this access.
