PMU: POWER UNIT、PWR I2C I/F

• Power Manager I2C Interface / I2C Interface
  The PXA27x processor contains a dedicated I2C module for communicating with an external regulator. “I2C Bus Interface Unit” for a full description. The only differences
  between the power manager I2C (PWR_I2C) and the standard I2C interfaces are the register addresses.
  

POWER MICRO: SSP I/F

• It is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the MCU achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
• The SSP ports are a synchronous serial interfaces that connect to a variety of external analog-todigital(A/D) converters, audio and telecommunication Codecs, and many other devices that useserial protocols for data transfer. The SSP ports provide support for the following protocols:
  • Texas Instruments (TI) Synchronous Serial Protocol
  • Motorola Serial Peripheral Interface (SPI) protocol
  • National Semiconductor Microwire
  • Programmable Serial Protocol (PSP)
  The SSP ports operate as full-duplex devices for the TI Synchronous Serial Protocol, SPI, and PSP protocols and as a half-duplex device for the Microwire protocol.
  The FIFOs can be loaded or emptied by the CPU using programmed I/O or by DMA burst
  transfers.
