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. The 23 GPIOs are multiplexed with:
- 7 of 8 chip selects.
- All seven external interrupts.
- All nine instruction trace pins.
Each GPIO output is separately programmable to emulate an open-drain driver (two states, drive to zero or
open circuit).
