REV. 5.1.0
ECP/EPP PARALLEL PRINTER PORT WITH 16-BYTE FIFO
4.0 DEVICE OPERATION
4.1
SPP MODE
This is ECR mode 000 (system RESET mode).
In this output-only mode the host data is registered to PD[7:0] at the trailing edge of -IOW; PDIR is driven low;
-STROBE, -AUTOFD, INIT, and -SLCTIN are open-drain; and all timing is managed by the host through DSR
and DCR registers.
4.2
PS2 MODE
This is ECR mode 001.
In this bi-directional mode the host output data is registered to PD[7:0] at the trailing edge of -IOW, PDIR is
driven by DIR to allow peripheral data input, -AUTOFD, INIT, and -SLCTIN are totem-pole, and all timing is
managed by the host through DSR and DCR registers.
4.3
PPF MODE
This is ECR mode 010.
In this output-only mode the host data is written to the FIFO with I/O writes to address 400 or by DMA writes;
PDIR is driven low; -AUTOFD, INIT, and -SLCTIN are totem-pole.
FIFO data is automatically registered to PD[7:0] whenever the FIFO-E bit is low (data available), and timing is
generated by controller logic that handshakes -STROBE (controller) with BUSY (peripheral).
4.4
ECP MODE
This is ECR mode 011.
In this bi-directional mode the host data is written to the FIFO with I/O writes to address 000, 400 or DMA;
PDIR is driven by DIR (can only be set in ECR mode 001); -AUTOFD, INIT, and -SLCTIN are totem-pole. I/O
writes to address 000 will write a low into the FIFO tag bit, while I/O writes to address 400 or DMA will insert a
high.
4.4.1
ECP FORWARD MODE (PDIR = 0)
FIFO data is automatically registered to PD[7:0] whenever the FIFO-E bit is low (data available), and timing is
generated by controller logic that handshakes -STROBE (controller) with BUSY (peripheral). Data from the
FIFO tag bit is output on -AUTOFD after being registered simultaneous with FIFO data.
