Revision A1
W83757 (SPP) mode: When this bit is a logic 1, pin PRTOE is high, and PRTBEN (CR3 bit 7)
is low, the parallel port is in input mode (read); when this bit is a logic 0, the parallel port is in
output mode (write). This bit is write-only.
BPP mode: When this bit is a logic 1, the parallel port is in input mode (read); when it is a logic
0, the parallel port is in output mode (write). This bit can be read and written.
Bit 4: A 1 in this position allows an interrupt to occur when
ACK
changes from low to high.
Bit 3: A 1 in this bit position selects the printer.
Bit 2: A 0 starts the printer (50 microsecond pulse, minimum).
Bit 1: A 1 causes the printer to line-feed after a line is printed.
Bit 0: A 0.5 microsecond minimum high active pulse clocks data into the printer. Valid data must be
present for a minimum of 0.5 microseconds before and after the strobe pulse.
5.2.4 EPP Address Port
The address port is available only in EPP mode. Bit definitions are as follows:
1
2
3
4
5
6
7
0
PD0
PD1
PD2
PD3
PD4
PD5
PD6
PD7
The contents of DB0-DB7 are buffered (non-inverting) and output to ports PD0-PD7 during a write
operation. The leading edge of
IOW
c
auses an EPP address write cycle to be performed, and the
trailing edge of
IOW
latches the data for the duration of the EPP write cycle.
PD0-PD7 ports are read during a read operation. The leading edge of IOR
causes an EPP address
read cycle to be performed and the data to be output to the host CPU.
5.2.5 EPP Data Port 0-3
These four registers are available only in EPP mode. Bit definitions of each data port are as follows:
1
2
3
4
5
6
7
0
PD0
PD1
PD2
PD3
PD4
PD5
PD6
PD7
When accesses are made to any EPP data port, the contents of DB0-DB7 are buffered (non-
inverting) and output to the ports PD0-PD7 during a write operation. The leading edge of IOW
causes
