External memory data bus: 16-bit data bus; used to connect to external RAM and
program memory
External memory data bus bit 14: 16-bit data bus; used to connect to external RAM
and program memory
Ground: 0 V reference
Main I/O power supply: 2.7 to 5.5 V operating range; main supply for the periphery
in normal operation
Power-down indicator: a LOW on this pin asserts an XA interrupt intended for use
as a power fail interrupt. Once reset is asserted, either by PWRFAIL or the firmware, it
will remain asserted until a set time after this pin goes HIGH.
External memory data bus bit 13: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 12: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 11: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 10: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 9: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 8: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 7: 16-bit data bus; used to connect to external RAM
and program memory
Ground: 0 V reference
Main I/O power supply: 2.7 to 5.5 V operating range; main supply for the periphery
in normal operation
External memory data bus bit 6: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 5: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 4: 16-bit data bus; used to connect to external RAM
and program memory
Ground: 0 V reference
Main core power supply: 2.7 to 3.6 V only; main supply for the core in normal
operation
External memory data bus bit 3: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 2: 16-bit data bus; used to connect to external RAM
and program memory
External memory data bus bit 1: 16-bit data bus; used to connect to external RAM
and program memory
