PC-TIO-10 User Manual

Interrupt Programming Example for the MC6821

The PC-TIO-10 is configured so that EXTIRQ1 on the I/O connector is connected to CA1 on the
MC6821, EXTIRQ2 on the I/O connector is connected to CB1 on the MC6821, and CA2 and
CB2 of the MC6821 are disabled.  The signal names CA1, CA2, CB1, and CB2 refer to the
names of pins located on the MC6821.  The names are given to clarify how the interrupt circuitry
is connected on the MC6821.  For more information on these signals, see Appendix D, Motorola
MC6821 Data Sheet.  Interrupts are enabled and disabled through the MC6821 Control Register.
In addition, the edge that generates the interrupt is programmable through the MC6821 Control
Register.

When an interrupt is generated (as indicated when the Control Register is read), the only way the
interrupt can be cleared is by reading the Output Register (through the Data Register) of the I/O
port that indicated the interrupt.  For instance, if IRQ in the Port B Control Register is set, you
must set DRS of the Port B Control Register to one, and then you must read the Port B Data
Register.  The data returned may not be important depending on how you are using interrupts.

The code that follows demonstrates how to set up the MC6821 for interrupt generation.
