DESCRIPTION
0 0 0 0 GPI GPI Digital input. DPIO_ logic-level read from DP_LL register bit.
0 0 0 1 WUL WUL
Digital input. A falling edge on WUL sets the OSCE bit enabling
the oscillator.
0 0 1 0 WUH WUH
Digital input. A rising edge on WUH sets the OSCE bit enabling
the oscillator.

0 1 0 0 SHDN SHDN
Digital input. A logic-low on SHDN overrides the register
settings and powers down all circuits. A logic-high on SHDN
transfers the power control back to the register settings.
0 1 0 1 DLAB DLAB
Digital input. A rising edge on DLAB shifts DACA and DACB
data from the input register to the output register or sequences
through FIFOA if enabled. For the MAX1330, this applies only
to DACA.
0 1 1 0 CONVST CONVST
Digital input. CONVST controls acquisition time and conversion
start. A falling edge on CONVST puts the ADC in acquisition
mode. A rising edge on CONVST starts a single conversion.
0 1 1 1 DLDA DLDA
Digital input. A rising edge on DLDA shifts DACA data from the
input to output register or sequences through FIFOA if enabled.
1 0 0 0 DSWA DSWA
Digital input. DSWA and OSW3 control the DACA and op amp 3
switches, respectively. See the Switch Control Register section.
1 0 0 1 DLDB —
Digital input. A rising edge on DLDB shifts DACB data from the
input to output register.
1 0 1 0 DSWB OSW2
Digital input. DACB and op amp 2 control the DACB and op
amp 2 switches, respectively. See the Switch Control Register
section.
1 0 1 1 OSW1 OSW1
Digital input. Op amp 1 switch control. See the Switch Control
Register section.
1 1 0 0 SPDT1 SPDT1
Digital input. SPDT1 controls the SPDT1 switch. See the Switch
Control Register section.
