Pin Description
40
44
GND
20
23
O
Signal and power ground.
RESET
21
24
I
Master reset (active high). A high on this pin will reset all the
outputs and internal registers.
-STROBE
22
25
I/O
General purpose I/O or strobe output (open drain active low, with
internal pull-up). To transfer latched data to the external peripheral
or printer.
-AUTOFDXT
23
26
I/O
General purpose I/O or line printer auto feed (open drain active
low, with internal pull-up). To signal the printer for continuous form
feed.
INIT
24
27
I/O
General purpose I/O or line printer initialize (open drain active
high, with internal pull-up). To signal the line printer to enter
internal initialization routine.
-SLCTIN
25
28
I/O
General purpose I/O or line printer select (open drain active low,
with internal pull-up). To select the line printer.
GND
26
30
O
Power and signal ground.
PD0-PD7
27-34
31-38
I/O
Bi-directional parallel ports (three state). To transfer data in or out
of the ST78C34 parallel port. PD7-PD0 are latched during output
mode.
A0-A1
36-37
40-41
I
Address lines. To select internal registers.
-IOW
38
42
I
Write strobe (active low). A low on this pin will transfer the contents
of the CPU data bus to the addressed register.
-IOR
39
43
I
Read strobe (active low). A low level on this pin transfers the
contents of the ST78C34 data bus to the CPU.
VCC
40
44
I
Power supply input.
