100 / 144 page  Complex bit access types are encoded to fit into small table cells. Table 8-94 shows the codes that are used for access types in this section. Table 8-94. DRV8714-Q1_STATUS Access Type Codes Access Type Code Description Read Type R R Read Reset or Default Value - n Value after reset or the default value 8.6.4.1.1 IC_STAT1 Register (Address = 0h) [reset = C0h] IC_STAT1 is shown in Table 8-95. Return to the Summary Table. Status register for global fault and warning indicators. Detailed fault information is available in remaining status registers. Table 8-95. IC_STAT1 Register Field Descriptions Bit Field Type Reset Description 7 SPI_OK R 1b Indicates if a SPI communications fault has been detected. 0b = One or multiple of SCLK_FLT in the prior frames. 1b = No SPI fault has been detected 6 POR R 1b Indicates power-on-reset condition. 0b = No power-on-reset condition detected. 1b = Power-on reset condition detected. 5 FAULT R 0b Fault indicator. Mirrors nFAULT pin. 4 WARN R 0b Warning indicator. 3 DS_GS R 0b Logic OR of VDS and VGS fault indicators. 2 UV R 0b Undervoltage indicator. 1 OV R 0b Overvoltage indicator. 0 OT_DRV_WD R 0b Logic OR of OTW, OTSD, STC_FLT, and WD_FLT indicators. 8.6.4.1.2 VDS_STAT1 Register (Address = 1h) [reset = 0h] VDS_STAT1 is shown in Table 8-96. Return to the Summary Table. Status register for the specific MOSFET VDS overcurrent fault indication for half-bridges 1-4. Table 8-96. VDS_STAT1 Register Field Descriptions Bit Field Type Reset Description 7 VDS_H1 R 0b Indicates VDS overcurrent fault on the high-side 1 MOSFET. 6 VDS_L1 R 0b Indicates VDS overcurrent fault on the low-side 1 MOSFET. 5 VDS_H2 R 0b Indicates VDS overcurrent fault on the high-side 2 MOSFET. 4 VDS_L2 R 0b Indicates VDS overcurrent fault on the low-side 2 MOSFET. 3 VDS_H3 R 0b Indicates VDS overcurrent fault on the high-side 3 MOSFET. 2 VDS_L3 R 0b Indicates VDS overcurrent fault on the low-side 3 MOSFET. 1 VDS_H4 R 0b Indicates VDS overcurrent fault on the high-side 4 MOSFET. 0 VDS_L4 R 0b Indicates VDS overcurrent fault on the low-side 4 MOSFET.
