• Manufacturer Part Number: mk68901
• Description: Multi.function Peripheral
• Manufacturer: STMicroelectronics

There are 16 vector addresses generated internally
by the MK68901, one for each of the 16 interrupt
channels.
The Interrupt Control Registers (figure 8) provide
control of interrupt processing for all I/O facilities of
the MK68901. These registers allow the program-

mer to enable or disable any or all of the 16 inter-
rupts, providing masking for any interrupt, and pro-
vide access to the pending and in-service status of
the interrupt. Optional end-of-interrupt modes are
available under software control. All the interrupts
