24-bit address bus
Indicates that a valid address is on the address bus
Requests an automatic vector during interrupt acknowledge
Indicates that a bus error has occurred
Indicates that the MCU has relinquished the bus
Indicates that an external device has assumed bus mastership
Signals a hardware breakpoint to the CPU
Indicates that an external device requires bus mastership
System clock output
Select external devices at programmed addresses
Chip select for external boot start-up ROM
16-bit data bus
During a read cycle, indicates when it is possible for an external
device to place data on the data bus. During a write cycle,
indicates that valid data is on the data bus.
Provide asynchronous data transfers and dynamic bus sizing
Serial I/O and clock for background debugging mode
a crystal or an external oscillator can be used
