CSI-2 Receiver Executes Software Reset Unconditionally
Low
Ongoing transactions may be interrupted when a software reset is performed while there is still active traffic generated by the CSI-2 receiver. Interruption of ongoing transactions typically leads to a general device hang that can only be recovered by a device reset.
Software must ensure that there is no ongoing traffic before performing a software reset. In particular, the CSI-2 receiver must be reset to resume normal operation after a CSI-2 FIFO overflow. There may be remaining data in the FIFO, and therefore ongoing traffic, when the software driver receives the overflow interrupt. To avoid creating a system hang, software must either:
