  • Page 150 J.1.2.3 Other phases Initialization phase: This phase includes both power-on initialization and host-driven interface reset. Negotiation phase: Signal handshaking to change the signaling method from Compatibility Mode to Nibble, Byte or other such modes. Power-on phase: This phase includes power-on initialization for both devices. Termination phase: A host-initiated transition phase in which the interface is changed from Nibble, Byte or other such Mode to Compatibility Mode.
  • Page 151 In this interface, the printer status after power-on sequence is available by checking Logic- HIGH. In 500 ms after Logic-HIGH exceeds High level (3.0 V) following the power-on sequence, all signals become active. The printer may be forcedly reset through the nInit signal. However, in either of the following conditions, the forced printer reset becomes inoperative and Low level pulses are ignored.
  • Page 152 J.2.3.2 Handshaking «...
  • Page 153 J.2.4.1 Description Normally the printer starts with Compatibility Mode in which it is Centronics interface compliant. In an attempt to transit to Nibble/Byte Mode, the printer proceeds with negotiation in response to the host request. Negotiation is proceeded as follows. 1) The host sets 1284-Active high to allow the interface to go to the Negotiation Phase.
  • Page 154 J.2.4.3 Notes 1) The start of negotiation phase shall be defined with 1284-Active triggered. 2) The timing to start negotiation in the Compatibility Mode shall be in principle after nAck pulse has been developed following nStrobe. Upon detection of 1284-Active before or during the output of nAck after nStrobe , the interface enters the negotiation phase.

  • Page 155: Options

    J.2.5.1 Nibble Mode 1) After negotiating to the Nibble Mode, the host will set HostBusy(nAutoFd) low to indicate it is ready to accept data from the printer (event 7). 2) The printer responds by placing the lower four bits on the Reverse channel data lines then sets PtrClk(nAck) low (event 8, event 9).
  • Page 156 12) Whenever the printer generates data for the host in the Reverse Idle phase, it sets PtrClk low to request an interrupt from the host (event 18). 13) Then, the printer sets PtrClk high (event 19). 14) The host responds to the interrupt requested by the printer by setting HostBusy(nAutoFd) high (event 20).
  • Page 157 10) When the printer has any additional data, the host is provided with three options as listed below. 1. To set HostBusy(nAutoFd) low, indicating that the host is ready to accept additional data. 2. To remain in the Host Busy Data Available phase. 3.
  • Page 158 Termination refers to the processing to return to the Compatibility Mode from either Nibble or Byte Mode. To terminate either the Nibble or Byte Mode, the host must take the following actions. • To set 1284-Active(nSelectIn) low. • To set HostBusy(nAutoFd) high (event 22). Termination is available in two types.
