The status3 command returns the chip-level status register of the MAX14819 transceiver. Unlike CMD_STATUS and CMD_STATUS2, this command is not port-specific and requires only a single command byte (no port index). The returned value is the content of the MAX14819 REG_Status register (0x1E) OR'd with any error bits that were latched since the last call to CMD_STATUS3. Reading this command clears the latch.
