Rev. B | Page 15 of 28
INTERNAL REGISTER STRUCTURE
The AD7291 contains 34 internal registers (see Figure 23) that
are used to store conversion results, high and low conversion
limits, and information to configure and control the device.
There are 33 data registers and one address pointer register.
Each data register has an address that the address pointer
register points to when communicating with it. Table 9 details
which registers are read, write, or read/write.
ADDRESS POINTER REGISTER
The address pointer register is the register to which the first
data byte of every write operation is written automatically;
therefore, this register does not have and does not require an
address. The address pointer register is an 8-bit register in
which the six LSBs are used as pointer bits to store an address
that points to one of the AD7291’s data registers. The first byte
following each write address is to the address pointer register,
containing the address of one of the data registers. The six LSBs
select the data register to which subsequent data bytes are
written. Only the six LSBs of this register are used to select a
data register. During power-up, the address pointer register
contains all 0s, pointing to the command register.
