6.3.1.4.2 Camera ISP Software Reset
A global software reset can be accomplished by setting the camera ISP
[1]
SOFT_RESET bit to 1. Setting this bit enables active software reset functionality equivalent to hardware
reset for the entire module, including CSI1/CCP2B,CSI2A, and CSI2C receivers.
NOTE:
The CSI1/CCP2B receiver accepts a general software reset, propagated through the
hierarchy. This reset can be performed to initialize the module and has the same effect as a
hardware reset.
The CSI1/CCP2B receiver can be reset by writing
[1] SOFT_RESET bit
to 1. The software can monitor the
[0] RESET_DONE status bit to wait
for the completion of the reset procedure.
If after five reads,
[0] RESET_DONE still returns 0, it can be assumed
that an error occurred during the reset stage.
