APTURE
(ECC)
This register contains information about the type and location of errors on the bus. The Error Code Capture Register
appears to the CPU as a read only memory.
Table 26
Error Code Capture (ECC) (CAN address 12)
Table 27
Description of Error Code Capture (ECC) Register 1 bits
Always if a bus error occurs, the corresponding bus error interrupt is forced, if enabled. In the same time, the current
position of the Bit Stream Processor is captured into the Error Code Capture Register. The content within this register is
fixed until the users software has read out its content once. From now on the capture mechanism is activated again.
The corresponding Interrupt Flag located in the Interrupt Register is cleared during the read access to the Interrupt
Register. A new Bus Error Interrupt is not possible until the Capture Register is read out once.
