67 / 156 page  ZAMC4100 Datasheet © 2016 Integrated Device Technology, Inc. 67 January 26, 2016 Important note: When the diagnostic circuitry is enabled (one of the HSxCSEN bits is set), then the corresponding over-current protection circuitry is not active. Therefore enabling the driver when the diagnostic circuitry is enabled is not recommended! Table 3.22 HSDSTAT Register Bits Mapping Name HSDSTAT Bit No 7 6 5 4 3 2 1 0 Bit name Reset 0 0 0 0 0 0 0 0 Access R R R R R/Wc R/Wc R/Wc R/Wc Address 0x0B R/Wc = Read/Write 1 to clear; R = Read-only bit Table 3.23 HSDSTAT Register Bits Description Bit Description 7:4 HSxOSF: Open/short status flag of the high-side driver x (x = 4 to 1). This flag is not registered; i.e., its value remains as long as the diagnostic event takes place. Refer to Table 3.24 for the descriptions of the HSxOSF bits. 3:0 HSxOCIF: Over-current interrupt flag of the high-side driver x (x = 4 to 1). 1 = There is an over-current in the output of driver x. The driver x is disabled as long as this bit is set. 0 = There is no over-current in the output of driver x. Table 3.24 High-Side Diagnostic Bits Description HSxCSHEN HSxOSF Description 1) 0 0 Normal load or short to VSS 2) 1 0 0 0 Open load 1 1 0 1 Short to VDDE 1 1 0 1 Not possible in normal application 1 0 1) Important: The diagnostic result is correct only if the corresponding driver is switched off. 2) In the event of a short, an over-current will occur. |
