General Purpose IO (GPIO) Controller
Controller functions and GPIO registers are programmed and accessed via memory-mapped OPB bus
master accesses
23 of 24 GPIOs are pin-shared with other functions. DCRs control whether a particular pin that has GPIO
capabilities acts as a GPIO or is used for another purpose. The 23 GPIOs are multiplexed with:
- 7 of 8 chip selects
- All 13 external interrupts
- All nine instruction trace pins
Each GPIO output is separately programmable to emulate an open-drain driver (i.e., drives to zero, three-
stated if output bit is 1)
Universal Interrupt Controller (UIC)
The Universal Interrupt Controller (UIC) provides the control, status, and communications necessary between
the various sources of interrupts and the local PowerPC processor.
Features include:
Supports 13 external and 19 internal interrupts
Seven of the 13 interrupts are mapped to the same GPIOs as the PPC405GP.
The other six interrupts can be mapped to any of the GPIOs.
Edge triggered or level-sensitive
Positive or negative active
Non-critical or critical interrupt to processor core
Programmable critical interrupt priority ordering
Programmable critical interrupt vector for faster vector processing
10/100 Mbps Ethernet MAC
Capable of handling full/half duplex 100Mbps and 10 Mbps operation
Uses the medium independent interface (MII) to the physical layer (PHY not included on chip)
JTAG
IEEE 1149.1 test access port
IBM RISCWatch debugger support
JTAG Boundary Scan Description Language (BSDL)
