405GP – Power PC 405GP Embedded Processor
IIC Bus Interface
General Purpose IO (GPIO) Controller
12
• Compliant with Philips® Semiconductors I
• Operation at 100kHz or 400kHz
• 8-bit data
• 10- or 7-bit address
• Slave transmitter and receiver
• Master transmitter and receiver
• Multiple bus masters
• Supports fixed V
• 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
• Controller functions and GPIO registers are programmed and accessed via memory-mapped OPB bus master
• 23 GPIOs are pin-shared with other functions. DCRs control whether a particular pin that has GPIO capabilities
• Each GPIO output is separately programmable to emulate an open-drain driver (i.e., drives to zero, three-
accesses
acts as a GPIO or is used for another purpose. The 23 GPIOs are multiplexed with:
stated if output bit is 1)
- 7 of 8 chip selects
- All seven external interrupts
- All nine instruction trace pins
