CONTROL REGISTER MAP DESCRIPTIONS
Table 43 through Table 49 provide a detailed description of each of the control register functions. The registers are listed by hexadecimal
address. A range of bits (for example, from Bit 5 through Bit 2) is indicated using a colon and brackets, as follows: [5:2].

Description
Bits[7:4] should always mirror Bits[3:0] so that it does not matter whether the part is in MSB or
LSB first mode (see Bit 1, Register 0x000). The user should set the bits as follows:
Bit 7 = Bit 0.
Bit 6 = Bit 1.
Bit 5 = Bit 2.
Bit 4 = Bit 3.
Short/long instruction mode. This part uses long instruction mode only, so this bit should
always be set to 1.
0: 8-bit instruction (short).
1: 16-bit instruction (long) (default).
Soft reset.
1: soft reset; restores default values to internal registers. Not self-clearing. Must be cleared to 0
to complete reset operation.
MSB or LSB data orientation.
0: data-oriented MSB first; addressing decrements (default).
1: data-oriented LSB first; addressing increments.
Selects unidirectional or bidirectional data transfer mode.
0: SDIO pin used for write and read; SDO set to high impedance; bidirectional mode (default).
1: SDO used for read, SDIO used for write; unidirectional mode.
Uniquely identifies the dash version (-0 through -4) of the AD9518.
AD9518-0: 0x21.
AD9518-1: 0x61.
AD9518-2: 0xA1.
AD9518-3: 0x63.
AD9518-4: 0xE3.
Selects register bank used for a readback.
0: reads back buffer registers (default).
1: reads back active registers.
