AR-B1570 User’s Guide 2.3 KEYBOARD CONTROLLER The 8042 processor is programmed to support the keyboard serial interface. The keyboard controller receives serial data from the keyboard, checks its parity, translates scan codes, and presents it to the system as a byte data in its output buffer. The controller can interrupt the system when data is placed in its output buffer, or wait for the system to poll its status register to determine when data is available. Data can be written to the

AR-B1570 User’s Guide 2.5 SERIAL PORT The ACEs (Asynchronous Communication Elements ACE1 to ACE4) are used to convert parallel data to a serial format on the transmit side and convert serial data to parallel on the receiver side. The serial format, in order of transmission and reception, is a start bit, followed by five to eight data bits, a parity bit (if programmed) and one, 1.5 (in a five-bit format only) or two stop bits(in a 6,7, or 8-bit format). The ACEs are capable of handling divis

AR-B1570 User’s Guide Bit 7: This signal may become active during data entry, when the printer is off-line during printing, or when the print head is changing position or in an error state. When Bit 7 is active, the printer is busy and cannot accept data. Bit 6: This bit represents the current state of the printers ACK signal. A0 means the printer has received the character and is ready to accept another. Normally, this signal will be active for approximately 5 microseconds before
