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
