440EPx – PPC440EPx Embedded Processor
Preliminary Data Sheet
18
AMCC Proprietary
Revision 1.26 – October 15, 2007
General Purpose IO (GPIO) Controller
Controller functions and GPIO registers are programmed and accessed via memory-mapped OPB bus master
accesses.
64 GPIOs are multiplexed with other functions. DCRs control whether a particular pin that has GPIO
capabilities acts as a GPIO or is used for another purpose.
Each GPIO output is separately programmable to emulate an open drain driver (that is, drives to zero,
tri-stated if output bit is 1).
Universal Interrupt Controller (UIC)
Two Universal Interrupt Controllers (UIC) are employed. They provide control, status, and communications
necessary between the external and internal sources of interrupts and the on-chip PowerPC processor.
Note:
Processor specific interrupts (for example, page faults) do not use UIC resources.
Features include:
10 external interrupts
Edge triggered or level-sensitive
Positive or negative active
Non-critical or critical interrupt to the on-chip processor
Programmable interrupt priority ordering
Programmable critical interrupt vector for faster vector processing
JTAG
Features include:
IEEE 1149.1 Test Access Port
JTAG Boundary Scan Description Language (BSDL)
