 UART IP

 

The IP provides two kinds of simplified interface connected to EMIF bus and AHB bus for communication with 8051 core and ARM core.The two kinds of interface are full-duplex serial communication interface.

 

Features

 

  • Support programmable baud rate
  • Synchronous mode, fixed baud rate
  • 5-bit, 6-bit, 7-bit, 8-bit data width, variable baud rate in mode 1
  • 9-bit UART mode, fixed baud rate
  • 9-bit UART mode, variable baud rate
  • 512-byte fifo for transmit & receive data path respectively, which can be configured by users
  • Support batch data read and receive overtime control(only for interrupt function) in mode 1
  • Support baud rate up to 115200bps
  • Support AHB interface and EMIF interface
  • Programmable BASE_ADDR for internal registers, EMIF interface address must be 0x20 aligned,AHB interface
     address must be 0x80 aligned.
