Description

This is about the same as NFCS:SendTagCommand, except that this verifies that the input/output buffer ptrs are not NULL. This also clears the output buffer before calling the cmd-sending func. A state field(probably TagState?) must match 3.

outputsize value 0x800 will be used when it's >=0x800.
