Data/Program Mode. This bit controls the operating mode of the AD73360. If CRA:1 is 0, then a 0 in this bit
places the part in Program Mode. If CRA:1 is 0, then a 1 in this bit places the part in Data Mode.
Mixed Mode. If this bit is a 0, then the operating mode is determined by CRA:0. If this bit is a 1, then the
part operates in Mixed Mode.
Reserved. This bit is reserved and should be programmed to 0 to ensure correct operation.
SPORT Loop Back. This is a diagnostic mode. This bit should be set to 0 to ensure correct operation.
Device Count Bits. These bits tell the AD73360 how many devices are used in a cascade. All devices in the
cascade should be programmed to the same value ensure correct operation. See Table XVIII.
Reset. Writing a 1 to this bit will initiate a software reset of the AD73360.
Decimation Rate. These bits are used to set the decimation of the AD73360. See Table VII.
Serial Clock Divider. These bits are used to set the serial clock frequency. See Table VI.
Master Clock Divider. These bits are used to set the Master Clock Divider ratio. See Table V.
Control Echo Enable. Setting this bit to a 1 will cause the AD73360 to write out any control words it receives.
This is used as a diagnostic mode. This bit should be set to 0 for correct operation in Mixed Mode or Data Mode.
