The CRC-32 calculation of the BGCRC module can be kicked off by configuring the register BGCRC_EN.START to 1010. Once started, the module performs the background memory checks without CPU or CLA intervention. However, on completion of the CRC-32 calculation or in the event of a failure, the CPU or CLA is notified through an interrupt and task, respectively.
As highlighted in the overview, there are two BGCRC modules. CPU_CRC that is configurable by the CPU can only generate an interrupt. CLA_CRC however, can be configured by both the CPU and CLA and can generate an interrupt to the CPU or task for the CLA.
