3.4.7 PCI_ERR_ADD register
The PCI_ERR_ADD register retains the PCI bus address when the following errors occur.
System error (SERR# reception)
Parity error (PERR# reception)
Master abort
Target abort
When the PCI_ERR_ADD register is read, all the bits are cleared. Once an error occurs and a value is set to the
PCI_ERR_ADD register, the first value is retained until read access is performed or a new error occurs and the value
is updated.
This function is used only for debugging and is not used in normal operation.
After reset: 00000000H R Offset address: 1CH
