DD
IIC interface
Two independent 4 x 1 byte data buffers
Twelve memory-mapped, fully programmable configuration registers
One programmable interrupt request signal
Provides full management of all IIC bus protocol
Programmable error recovery
General Purpose IO (GPIO) Controller
Controller functions and GPIO registers are programmed and accessed via memory-mapped OPB bus
master accesses
All GPIOs are pin-shared with other functions. DCRs control whether a particular pin that has GPIO capabil-
ities acts as a GPIO or is used for another purpose.
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 seven external and 19 internal interrupts
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
