MC68SEC000 PRODUCT INFORMATION
5
Interrupt Control
The MC68SEC000 provides seven levels of interrupts. The interrupt priority level (IPL2, IPL1, IPL0) inputs
determine the priority level. Level 7 is nonmaskable and is the highest priority interrupt. Automatic vectoring,
based on IPL inputs, is available with the autovector (AVEC) input.
System Control
The system control inputs include the RESET, HALT, BERR, and MODE signals. These signals can reset
or halt the controller, indicate to the controller that a bus error has occurred, and select from 8- or 16-bit
operating mode.
Processor Status (FC2, FC1, FC0)
These active-high, three-state function code outputs indicate the mode (user or supervisor) and the address
space currently being accessed. The function code outputs are valid whenever AS is active.
