STR720 - ASYNCHRONOUS AHB-APB BRIDGE (A3BRG)

164/401

Peripherals Address Error Register (PAER)

Address Offset: 08h

Reset value: 0x0000_0000

Bit 31:25 = Reserved. These bits must be always written to and read back as ‘0’.

Bit 24= nRW: access type.

It returns the type of access that generate the error conditions: read(0) or write(1)

Bit 23:0 = Peripheral Address.

The Bridge is able to detect some errors while accessing to a peripherals. If an error occurs,

the bridge ends the APB transaction and reports on the AHB bus an ERROR condition (if

enabled). The address of slave generating the error condition is reported in the PERIPHERAL

ADDRESS field. Depending of the size of the AHB addressing space, the MSB can be filled

with 0.
