PURPOSE: To decide a response message, command by making an ordered character set have a multiple bit idle character in the first character and a command character in the second character. CONSTITUTION: When FUNCTION OUT is detected, a state machine 330 shifts to a state 1. When the machine 1 is in the state 1 and receives K28.5<-> to be detected by an AND gate 326, it shifts to a state 0. When it is in the state 0 and K28.5<+> is detected or when it is in the state 1 and K28.5<+> is detected, an error is shown. When it is in the state 0 or in the state 1 and a subblock is detected by the AND gate, the MSB(most significant bit) of a data character is latched as a FUNCTION, OUT message. |
