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) and TOR
(Chapter 12.2.4.3).
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. The separation in two
diagnosis register banks allows together with the Device Control Bits “Latch on Over Current or Over Temperature”
[LOTC] a separated handling of the channel groups. The groups of Channel 1 to 6 and 7 to 10 can be treated
separately in this case. For details, see also chapter Chapter 12.3.6.
