REGISTERS
The AD7322 has two programmable registers, the control
register and the range register. These registers are write-only
registers.
ADDRESSING REGISTERS
A serial transfer on the AD7322 consists of 16 SCLK cycles. The
three MSBs on the DIN line during the 16 SCLK transfer are
decoded to determine which register is addressed. The three
MSBs consist of the write bit, zero bit, and register select bit.
The register select bit is used to determine which of the two on-
board registers is selected. The write bit determines if the data
on the DIN line following the register select bit loads into the
addressed register. If the write bit is 1, the bits are loaded into
the register addressed by the register select bits. If the write bit
is 0, the data on the DIN line does not load into any register.
The zero bit must always be set to 0.
Combinations of the write bit, the zero bit, and the register
select bit other than those specified in Table 8 access registers
for Analog Devices internal use only. Do not access these registers,
as doing so may lead to unspecified operation of the device.
