User can store any of the 64 RDAC settings for AD5251 or any of the 256
RDAC settings for AD5252.
RDAC/EEMEM Read
The AD5251/AD5252 provide two different RDAC or EEMEM
read operations. For example, Figure 9 shows the method of
reading the RDAC0 to RDAC3 contents without specifying the
address, assuming Address RDAC0 was already selected from
the previous operation. If RDAC_N, other than Address 0, is
selected previously, readback starts with Address N, followed by
N + 1, and so on.
Figure 10 illustrates a random RDAC or EEMEM read
operation. This operation lets users specify which RDAC or
EEMEM register is read by first issuing a dummy write
command to change the RDAC address pointer, and then
proceeding with the RDAC read operation at the new address
location.
