PauseLong
Forces the chip into the pause state until the watchdog timer expires, after which it will automatically enter into the sleep state.
During execution of this command the chip will ignore all activity on the IO signal. This command is used to prevent bus
conflicts in a system that also includes the CryptoAuthentication host chip sharing the same signal wire.

only if those fuse values match the least significant four bits of the selector parameter. If the chip does not go into
the pause state, it returns an error code of 0x0F. Otherwise, it goes into the pause state and never returns any code.
