Channel n Security Attribution [n=0..7]

The bit n of CHANNEL enables the non-secure mode of CHANNELn. The registers whose CHANNEL bit or bitfield n is set in non-secure mode by NONSECCHAN.CHANNELn are CHANNELn, CHINTENCLRn, CHINTENSETn, CHINTFLAGn and CHSTATUSn registers.

These bits set the security attribution for the individual channels.
