摘要： A serial protocol which enables a printer control unit (102) to communicate with a number of printheads (104-110) over a clock wire (116) and a data wire (114). In sync with pulses on the clock wire, the printer control unit transmits the following bits over the data wire: at least one read/write bit, at least one pen ID (which identifies one or more of the printheads), at least one address bit, and at least one data bit. The printheads determine whether the transmitted pen ID matches their own pen ID. If so, and the at least one read/write bit transmitted by the printer control unit is indicative of a read operation, a printhead will read data from a register (404) which is determined by the at least one address bit transmitted by the printer control unit, and then output the read/write bit, the at least one pen ID bit, the at least one address bit, and the data read from its register to the printer control unit. The bits will be output on the data wire, and will be transmitted in sync with pulses on the clock wire. If the pen ID transmitted by the printer control unit matches a given prinhtead's pen ID, and the read/write bit transmitted by the printer control unit is indicative of a write operation, the printhead will write the data it receives from the printer control unit to a register which is addressed by the printer control unit. The printhead will also output the read/write bit, the at least one pen ID bit, and the at least one address bit to the printer control unit. The printhead may also read the data it has just written to one of its registers, and output the read data to the printer control unit as a form of write verification.
摘要翻译：一种使打印机控制单元（102）能够通过时钟线（116）和数据线（114）与多个打印头（104-110）通信的串行协议。与时钟线上的脉冲同步，打印机控制单元通过数据线发送以下位：至少一个读/写位，至少一个笔ID（识别一个或多个打印头），至少一个地址位和至少一个数据位。打印头确定所发送的笔ID是否与自己的笔ID相匹配。如果是，并且由打印机控制单元发送的至少一个读/写位表示读操作，则打印头将从由打印机发送的至少一个地址位确定的寄存器（404）读取数据控制单元，然后将读/写位，至少一个笔ID位，至少一个地址位和从其寄存器读取的数据输出到打印机控制单元。这些位将在数据线上输出，并与时钟线上的脉冲同步发送。如果由打印机控制单元发送的笔ID与给定的原始笔ID相匹配，并且由打印机控制单元发送的读/写位表示写入操作，则打印头将其从打印机控制单元接收的数据写入由打印机控制单元寻址的寄存器。打印头还将将读/写位，至少一个笔ID位和至少一个地址位输出到打印机控制单元。打印头也可以读取其刚刚写入其寄存器之一的数据，并将读取的数据作为写入验证的形式输出到打印机控制单元。
