Title
When using the SDI RX and TX MegaCore function (independent RX & TX instances packed into the same channel), can I reset only the RX instance (during detect video format change)?
Description
Yes, the RX instance is reset internally during RX reconfiguration (when a video format change is detected). The TX instance does not require reset during RX reconfiguration if TX remains unaltered.
Note: The SDI TX MegaCore® function does not support automatic reset for TX reconfiguration.
You must design additional user logic to perform reset for TX reconfiguration if this functionality is required.
The sdi_start_reconfig signal can be used to reset the TX while RX is being reconfigured if required.
