REGISTER BIT DESCRIPTIONS
The serial I/O port registers span an address range of 0 to 25
(0x00 to 0x19 in hexadecimal notation). This represents a total
of 26 registers. However, six of these registers are unused
yielding a total of 20 available registers. The unused registers are
7, 8, 11 to 13, and 23 (0x07 to 0x08, 0x0B to 0x0D, and 0x17).

The number of bytes assigned to the registers varies from
register to register. That is, the registers are not of uniform
depth; each contains the number of bytes necessary for its
particular function. Additionally, the registers are assigned
names according to their functionality. In some cases, a register
is given a mnemonic descriptor. For example, the register at
Serial Address 0x00 is named Control Function Register 1 and
is assigned the mnemonic CFR1.
The following section provides a detailed description of each bit
in the AD9957 register map. For cases in which a group of bits
serve a specific function, the entire group is considered as a
binary word and described in aggregate.
This section is organized in sequential order of the serial
addresses of the registers. Following each subheading are the
individual bit descriptions for that particular register. The
location of the bit(s) in the register are indicated by <A> or
<A:B>, where A and B are bit numbers. The notation, <A:B>,
specifies a range of bits from most significant to least significant
bit position. For example, <5:2> means bit positions 5 down to
2, inclusive, with bit 0 identifying the LSB of the register.
Unless otherwise stated, programmed bits are not transferred to
their internal destinations until the assertion of an I/O update or
profile change.
