REGISTER BIT NAME DESCRIPTION
COMMS 0/DRDY Start bit is zero; DIN pin must be 1 when idle
RS2–RS0 Register select for subsequent operation
R/W
Selects subsequent read or write operation
RESET Causes software reset when set to 1
STDBY Activates standby power-down mode when set to 1
FSYNC Inhibits the A/D converter when set to 1
GS1 A1 Selects the active channel
A0 Selects the active channel
MF1 Selects the data output rate

GS2 SCAN Enables the scanning sequences
M1 Enables the CalGain channel
M0 Enables the CalOff channel
BUFF Enables the input buffers
DIFF Selects differential input pairs
BOUT Enables the transducer burn-out test currents
IOUT Enables the OUT1 and OUT2 current sources (MAX1402 only)
