EXTERNAL CONNECTIONS
External Interface Connections are made
from the three 26-pin edge connectors at
the top of. the board. These contain the
signals necessary for two identical para
llel interfaces, and a serial I/O inter
face. The Current Loop or EIA options
are normally configured to provide a stan
dard EIA Data Transmission pinout at the
connector.
INTERRUPT CAPABILITIES
Any of the Status Signals from each of
the I/O Ports may be used to generate
Interupts. Provision is made for jumpering
these Status Signals to Vectored,.Interrupt
Lines, if a PIC-8 Board is present;.
They may be directly jumpered. . . to _.the CPU
Interrupt Line for a single level Inter- .
rupt System.
SERIAL INPUT/OUTPUT- PORT
The MIO Board provides for one complete
Serial I/O port which is designed to re
quire no initialization on power-up.
BOARD OPTIONS
A number of options are available and are
easily selected by the User.
1. The Baud Rate is jumper selectable
and can range from 45.5 to 9600 Baud.
2. Character Length, Parity Enable,
and Even/Odd Parity selection are
