The ADAV801 provides the user with the ability to write to or
read from a block of registers in one continuous operation. In
SPI mode, the CLATCH line should be held low for longer than
the 16 CCLK periods to use the block read/write mode. For a
write operation, once the LSB has been clocked into the
ADAV801 on the 16th CCLK, the register address as specified
by the first seven bits of the write operation is incremented and
the next eight bits are clocked into the next register address.
The read operation is similar. Once the LSB of a read register
operation has been clocked out, the register address is
incremented and the data from the next register is clocked out
on the following eight CCLKs. Figure 55 and Figure 56 show the
timing diagrams for the block write and read operations.
