Setting the Address  
The base address of the PIOC is set using a eight-position DIP  
switch, SW1. The eight positions correspond to the I/O address lines  
of A2 through A9 (see Table 2). If you set the a switch OFF the  
corresponding I/O address line will be a ZERO and if you set it ON  
the corresponding I/O address line will be a ONE. The factory  
default address setting is 378h. To set the card to the 378h address  
you must set A2 and 7 OFF and A3, 4, 5, 6, 8, and 9 ON. Table 3  
shows the settings for LPT1 and LPT2.

Using the PIOC as I/O  
The PIOC may also be used as a general I/O device. The Base  
Register has eight bi-directional lines. The direction of these lines is  
based on bit 5 of the Control Register. If bit 5 of the Control Register  
is a “1”, then the lines of the Base Register are defined as inputs. If  
bit 5 of the Control Register is a “0”, then these lines are defined as  
outputs (this is default state after “boot up”). If the Base Register is  
being used as outputs, the states of the lines can be changed by  
writing (outputting) to the Base Register. The states of these lines  
can be determined by reading (inputting) the Base Register. Writing  
(outputting) to the Base Register when the lines are defined as  
inputs will have no affect on the port. Table 5 shows the functions of  
the registers and their pinouts.  
The five lines of the Status Register can only be used as inputs.  
The four lines of the Control Register can be used as inputs or  
outputs. The Control Register can be used as inputs by writing  
(outputting) a byte with the following bit pattern “xxxx0100” (4h) to  
the Control Register where “x” is a don’t care. Caution should be  
taken to insure bits 4 and 5 remain in the desired state (See Notes 2  
and 3). The states of these lines can be determined by reading  
(inputting) the Control Register. The lines of the Control Register  
can be used as outputs by writing (outputting) to the Control  
Register.

NOTE 1: An "X" means no connection to any DB-25 pins.  
NOTE 2: Bit 4 of the Control Register (37AH) as an output is used  
to control IRQ7. When this bit is high, IRQ7 is enabled and when  
this bit is low, IRQ7 is disabled. As an input this reads the status of  
the Interrupt Enable.  
NOTE 3: This bit is used to control the direction of the Base  
Register (378H). Outputting a “1” to this bit defines the lines as  
inputs. Outputting a “0”, which is default, to this bit defines the lines  
as outputs.
