### Is protected

Checks whether the device's protected bit is set. When using aWire the explicit isProtected command is called. When using JTAG the MEMORY_WORD_ACCESS instruction is clocked into the IR. The pattern "peb01" is clocked out during this operation. The value of "p" is returned, or a failure returned if the "01" token is not received.
