Control of the device

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 recieved 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 tDidle needs to elapse, from

the CS low-to-high transition of the clear command, before the register content is effectively cleared

(Figure 39); This time has to be taken into account when trying to read the Diagnosis register content after a

clear, see Chapter 11.3 for tDidle defintion.

After an overcurrent entry is stored in the diagnosis register (OC), the idle time tOCidle 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 39), 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 tOCidle defintion.

Description

INx Input Pin Status

The Status of the INx Pins is read out at the moment of CS High-to-

Low transition. Details see Figure 38.

INx = Low corresponding OFF

1INx = High corresponding ON
