Use the DIOConfig register to control the DI and DO interfaces. All bits in the DIOConfig register are read-write and
are set to 0 at power-up.
BIT
NAME
DESCRIPTION
D7
DoInv
DO Output Polarity. Set the DoInv bit to 1 to invert the logic of the DO
output. This bit also works in conjunction with the DoAv (Table 6). DO
tracks the TXC and TXQ inputs with the opposite polarity when both the
DoAv and DoInv bits are set.
D6
DoAv
DO Antivalent Operation. Set the DoAv bit to 1 to enable antivalent
output operation on DO. DO tracks the TXC and TXQ inputs (and the Q
bit) when DoAv is 1 (Table 6).
The LO input and the DoBit are ignored when the DoAv bit is 1.
D5
DoN/P
DO Driver NPN/PNP Operation. The DoN/P bit selects between low-
side (NPN) and high-side (PNP) modes when the DO driver is configured
as an open-drain output (DoPP = 0). Set DoN/P to 1 to configure the
driver for low-side (NPN) operation. Set DoN/P to 0 for high-side (PNP)
operation.
D4
DoPP
DO Driver Push-Pull Operation. Set the DoPP bit to 1 to configure the
DO driver output for push-pull operation. DO is an open-drain output
when DoPP is 0.
D3
DoEn
DO Driver Enable/Disable. Set the DoEn bit to 1 to enable the DO
driver. The DO driver is high impedance with a weak pulldown when
DoEn is 0.
D2
DoBit
DO Driver Output Logic. The DoBit bit can be used to program the
DO output driver through software. Drive LO high to activate DoBit
programming (Figure 9). The DO output state is given in Table 7. Note
that Table 7 assumes that the DoInv bit is 0.
D1
LiDis
LI Output Enable/Disable. Set the LiDis bit to 1 to disable the LI output.
The LI output is low when LiDis is 1.
D0
DiLoad
DI Current Sink Enable. Set the DiLoad bit to 1 to enable the internal
current sink at the DI input.
