Description
Enables SPI port SDO pin. This bit does nothing in I²C mode.
1 = 4-wire (SDO pin enabled).
0 = 3-wire (default).
Bit order for the SPI port. This bit is nonfunctional in I²C mode.
1 = LSB and byte first. Register addresses are automatically incremented in multibyte
transfers.
0 = MSB and byte first (default). Register addresses are automatically decremented in
multibyte transfers.
Device reset.
Reserved.
Same function as Bit 5 of this register, set Bit 2 and Bit 5 to the same value.
Same function as Bit 6 of this register, set Bit 1 and Bit 6 to the same value.
Same function as Bit 7 of this register, set Bit 7 and Bit 0 to the same value.
Description
A read-only register. Identifies the revision level of the AD9508.
0x00 = default.
A read-only register. This register, together with Register 0x000D, uniquely identifies an
AD9508. No other device in the Analog Devices, Inc., AD95xx family has a value of 0x0005 in
these two registers.
0x05 = default.
This register is a continuation of Register 0x000C.
0x00 = default.
Description
0x00000010 = default
0x000 = default
0 = disables sleep mode (default)
1 = enables sleep mode
0x0000 = default
0x0000000 = default
0 = enables a software output synchronization routine
1 = output synchronization via software disabled (default)
