DD
IIC interface
Two independent 4 x 1 byte data buffers
Twelve memory-mapped, fully programmable configuration registers
One programmable interrupt request signal
Full management of all IIC bus protocols
Programmable error recovery
Port 0 supports serial Bootstrap ROM with default parameters override at initialization
General Purpose Timers (GPT)
Provides a time base counter and system timers additional to those defined in the processor core.
32-bit time base counter driven by the OPB bus clock
Seven 32-bit compare timers
General Purpose IO (GPIO) Controller
Controller functions and GPIO registers are programmed and accessed by means of memory-mapped OPB
bus master accesses.
The 32 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.
Each GPIO output is a separately programmable tri-state driver (pull-up, pull-down, or open-drain).
