Figure 28 General Configuration Register

MOSI

• B12 - B6: Not used, Ignored - Don’t Care

• B5 Fault Typing Bit: Activates a 40 μA pull-up current on POSx pin for SG/OL

differentiation. Default = 0 (disabled)

• B4 - B3 Slew Rate: Setting for the slew rate (see Table 5). Default = 3 (1.2 V/μs)

• B2 - B0 Switching Hysteresis: Setting for the hysteresis value (see Table 6),

Default = 0 (40 mVpp)

MISO

• B12 OL/SG: Open Load / Short to Ground fault flag

• B11 VSHT: Short to BAT (Shorted Load) fault flag

• B10 OTMP: Overtemperature fault flag

• B9 - B7: Not used, always 0

• B6 REF: = 0 when an external reference is detected on the REF pin,

B6 REF: = 1 when the REF pin is grounded and the internal 2.5 V reference is active

• B5 FT: Contents of the FT-bit in the general configuration register

• B4 - B3 Slew Rate: Contents of the Slew Rate settings in the general configuration

• B2 - B0 SW: Contents of the switching hysteresis setting in the general configuration
