3.6.4. Parallel Interface
This interface conforms the IEEE1284 standard and the data transferring to host PC and data receiving from host PC are mainly
operated by the ASIC1 (IC15). The data lines (data0 ~ data7) and control lines (nStrobe, nACK, Busy, etc) are connected from the
parallel interface connector CN1 on the main control board to the ASIC1 through the IEEE1284 driver IC3. The signal level is 3.3V
on the signal lines that connect the IC3 and ASIC1, and is 5V on the signal lines that connect the IC3 and connector CN1. Part of
signal lines are connected to the ASIC1 through IC11 for performing the firmware controlled the printer status at ECP mode. The
signal EEPDATA2 (pin 104 of ASIC2) is used as the busy control signal. This signal is sent to ASIC1 (pin AD7) from IC11 (pin 36)
as the signal HSTCK2. The signal nSelIn is connected to the ASIC1 through IC11 because IC11 has the circuit for conforming the
ECP transferring without the negotiation (abnormal data transferring).
The following timing chart indicates the timing regarding the data and control signals at compatible mode.
After the Busy is asserted according to the signal nStrobe from the host PC, the data is fetched when the signal nStrobe raises.
After the fetched data is stored, the signal nAck is asserted to complete the 1 byte data transferring. Refer to the IEEE1284
standard regarding the timing for the nibble and ECP transferring modes.
