REGISTER BIT DESCRIPTIONS
The serial I/O port registers span an address range of 0 to 23
(0x00 to 0x16 in hexadecimal notation). This represents a total
of 24 registers. However, two of these registers are unused,
yielding a total of 22 available registers. The unused registers are
Register 5 and Register 6 (0x05 and 0x06, respectively).
The number of bytes assigned to the registers varies. 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 AD9910 register map. For cases in which a group of bits
serves a specific function, the entire group is considered a
binary word and described in aggregate.
This section is organized in sequential order of the serial addresses
of the registers. Each subheading includes the register name and
optional register mnemonic (in parentheses). Also given is the
serial address in hexadecimal format and the number of bytes
assigned to the register.
Following each subheading is a table containing the individual
bit descriptions for that particular register. The location of the
bit(s) in the register is indicated by a single number or a pair of
numbers separated by a colon; that is, a pair of numbers (A:B)
indicates a range of bits from the most significant (A) to the
least significant (B). For example, 5:2 implies Bit Position 5
down to Bit Position 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 the I/O_UPDATE
pin or a profile change.
Control Function Register 1 (CFR1)—Address 0x00
Four bytes are assigned to this register.
Table 18. Bit Description for CFR1
Bit(s)
Mnemonic
Description
31
RAM enable
0 = disables RAM functionality (default).
1 = enables RAM functionality (required for both load/retrieve and playback operation).
30:29
RAM playback destination
See Table 12 for details; default is 00b.
28:24
Open
23
Manual OSK external
control
Ineffective unless CFR1[9:8] = 10b.
0 = OSK pin inoperative (default).
1 = OSK pin enabled for manual OSK control (see Output Shift Keying (OSK) section for
details).
22
Inverse sinc filter enable
0 = inverse sinc filter bypassed (default).
1 = inverse sinc filter active.
21
Open
20:17
Internal profile control
Ineffective unless CFR1[31] = 1. These bits are effective without the need for an I/O update.
See Table 14 for details. Default is 0000b.
16
Select DDS sine output
0 = cosine output of the DDS is selected (default).
1 = sine output of the DDS is selected.
15
Load LRR @ I/O update
Ineffective unless CFR2[19] = 1.
0 = normal operation of the digital ramp timer (default).
1 = digital ramp timer loaded any time I/O_UPDATE is asserted or a PROFILE[2:0] change
occurs.
14
Autoclear digital ramp
accumulator
0 = normal operation of the DRG accumulator (default).
1 = the ramp accumulator is reset for one cycle of the DDS clock after which the accumula-
tor automatically resumes normal operation. As long as this bit remains set, the ramp
accumulator is momentarily reset each time an I/O_UPDATE is asserted or a PROFILE[2:0]
change occurs. This bit is synchronized with either an I/O _UPDATE or a PROFILE[2:0]
change and the next rising edge of SYNC_CLK.
13
Autoclear phase
accumulator
0 = normal operation of the DDS phase accumulator (default).
1 = synchronously resets the DDS phase accumulator anytime I/O_UPDATE is asserted or a
profile change occurs.
