Serial Port
Features include:
IIC Bus Interface
Features include:
General Purpose Timers (GPT)
Provides a separate time base counter and additional system timers in addition to those defined in the processor
core.
General Purpose IO (GPIO) Controller
• Support for peripherals running on slower frequency buses
• One 8-pin UART and one 4-pin UART interface provided
• Selectable internal or external serial clock to allow wide range of baud rates
• Register compatibility with 16750 register set
• Complete status reporting capability
• Fully programmable serial-interface characteristics
• Supports DMA using internal DMA engine
• Two IIC interfaces provided
• Support for 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 protocols
• Programmable error recovery
• 32-bit Time Base Counter driven by the OPB bus clock
• Seven 32-bit compare timers
• Controller functions and GPIO registers are programmed and accessed via memory-mapped OPB bus master
• The 32 GPIOs are pin-shared with other functions. DCRs control whether a particular pin that has GPIO
• Each GPIO output is separately programmable to emulate an open drain driver (that is, drives to zero,
accesses.
