31-9 Reserved 0 Reads return 0. Writes have no effect.
8 CH2_PSA_SWREST Channel 2 PSA Software Reset. When set, the PSA Signature Register is reset to all zero.
Software reset does not reset software reset bit itself. Therefore, CPU is required to clear
this bit by writing a 0.
0 PSA Signature Register is not reset.
1 PSA Signature Register is reset.
7-1 Reserved 0 Reads return 0. Writes have no effect.
