12.3.2 DCC - Diagnosis Registers and compactCONTROL
The DCC - Diagnosis and Compact Control Set allows to read out and clear the Diagnosis Registers. Additionally
this Command set offers the possibility to proceed with a compactCONTROL Mode using DMS - Diagnosis Mode
Set and OPS - Output Pin Set Commands. This compactCONTROL Mode offers the possibility to Control the
device with lowest work load on the micro controller side.
If any other pattern then the defined commands is received on S_SI, the command is ignored and rated as a
Communication Error. In this case, this incident is reported in SDS (Chapter 12.3.1.2).
If an Error in the Output Channels is detected by the diagnosis circuit, the result is latched in the diagnosis registers
related to each channel.
The Diagnosis Register is not deleted, when it is just read out. The Diagnosis Register byte can only be cleared
by using the appropriated command. In this case, the complete Register Bank is cleared.
When issuing a Diagnosis Register Clear command (DRxCL or DMSCL), the idle time t_Didle needs to elapse, from
the CS low-to-high transition of the clear command, before the register content is effectively cleared (Figure 40);
this time has to be taken into account when trying to read the Diagnosis register content after a clear, see
Chapter 11.3 for t_Didle definition.
After an overcurrent entry is stored in the diagnosis register (OC), the idle time t_OCidle needs to elapse before a
clear command can effectively clear the entry; if trying to clear the Diagnosis register after an OCT entry is read
(Figure 40), this time has to be taken into account starting from the CS high-to-low transition of the previous read
command, see Chapter 11.3 for t_OCidle definition.
