RMNSq Flags (q = 0 to 31)
Each RMNS flag is set to 1 when the processing for storing a message in the corresponding receive
buffer starts.
To clear a flag to 0, the program must write 0 to the flag. Use a store instruction to write "0" to the flag
and "1" to other flags. These bits cannot be set to 0 while a message is being stored. It takes ten clock
cycles of pclk to store a message.
These flags are cleared to 0 in global reset mode.
