REGISTER MAP DESCRIPTIONS
Table 50 through Table 60 provide a detailed description of each of the control register functions. The registers are listed by hexadecimal
address. Reference to a specific bit or range of bits within a register is indicated by squared brackets. For example, [3] refers to Bit 3 and
[5:2] refers to the range of bits from Bit 5 through Bit 2.

Description
Selects unidirectional or bidirectional data transfer mode.
[7] = 0; SDIO pin used for write and read; SDO is high impedance (default).
[7] = 1; SDO used for read; SDIO used for write; unidirectional mode.
SPI MSB or LSB data orientation. (This register is ignored in I
[6] = 0; data-oriented MSB first; addressing decrements (default).
[6] = 1; data-oriented LSB first; addressing increments.
Soft reset.
[5] = 1 (self-clearing). Soft reset; restores default values to internal registers.
Bits[3:0] should always mirror[7:4] so that it does not matter whether the part
is in MSB or LSB first mode (see Register 0x000[6]). Set bits as follows:
[0] = [7]
[1] = [6]
[2] = [5]
[3] = [4]
Select register bank used for a readback.
[0] = 0; read back buffer registers (default).
[0] = 1; read back active registers.

[0] = 1; read back active registers.
Description
16-bit EEPROM ID[7:0]. This register, along with 0x006, allows the user to store a
unique ID to identify which version of the AD9520 register settings is stored in the
EEPROM. It does not affect AD9520 operation in any way (default: 0x00).
16-bit EEPROM ID[15:8]. This register, along with 0x005, allows the user to store a
unique ID to identify which version of the AD9520 register settings is stored in the
EEPROM. It does not affect AD9520 operation in any way (default: 0x00).
