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, indi-
cates 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
Identify processor state and current address space
Indicates that the CPU has entered background mode
Suspend external bus activity
Indicate instruction pipeline activity
Provides an interrupt priority level to the CPU
Serial input to QSPI in master mode;
serial output from QSPI in slave mode
Selects the source and type of system clock
Serial output from QSPI in master mode;
serial input to QSPI in slave mode
