PURPOSE:To make the editing control of a Kanji printer controller possible, by setting states of function code registers by not only the function code on a data stream but also commands. CONSTITUTION:The function code taken out from a data stream by a discriminator 6 is set to a function code register group 3 through a gate group 4. However, when effective information, namely, the function code is set to a receiving register 1 by a command, contents of the receiving register 1 are set preferentially to the function code register group 3 through the gate group 4. When a reset command is issued, the function code register group 3 is set to the initial state by the output of a receiving register 5 which receives the reset signal of the receiving register 1. |
