4.3. Bus Diagnosis Address Register : BUSADR
This section explains the bus diagnosis address register.
If an address parity error, data parity error, or control parity error is detected, the bus diagnosis address
register (BUSADR) stores the relevant address. This register is valid when the DER, AER, or CNER bit of
the bus diagnosis status register (BUSDIGSR) is "1".
Bus diagnosis address register 0 indicates an address in which an AHB diagnosis error was detected. Bus
diagnosis address register 1 indicates an address in which an APB (PCLK2) diagnosis error was detected.
Bus diagnosis address register 2 indicates an address in which an Rbus (PCLK2) diagnosis error was
detected. Bus diagnosis address register 3 indicates an address in which an APB (PCLK1) diagnosis error
was detected. Bus diagnosis address register 4 indicates an address in which an Rbus (PCLK1) diagnosis
error was detected.
