Universal Asynchronous Receive Transmit(UART2) 

26.1

 

Introduction 

The  UART2  supports  Asynchronous  one-way  communication,  half-duplex  single  wire 

communication, and without CTS/RTS. UART2 is called the simple UART.

 

26.2

 

Feature 

-

 

Serial-to-parallel conversion on data received from a peripheral device 

-

 

Parallel-to-serial conversion on data transmitted to the peripheral device 

 

26.3

 

Functional description 

UART bidirectional communication requires a minimum of two pins: RX, TX 

The frame are comprised of: 

 

An Idle Line prior to transmission or reception   

 

The UART interface uses a baud rate generator   

 

A status register (UART2_SR)   

 

data registers (UART2DR) 

 

A baud rate register (UART2_B,UART1_FBRD) 

Baud rate calculation 

UART2 can operate with or without using the Fractional Divider. The baud rate divisor is a 20-

bit number consisting the UART2BDR. 

  This is used by the baud rate generator to determine the bit period.

Baud Rate Divisor =

UARTCLK

(𝑏𝑎𝑢𝑑 𝑟𝑎𝑡𝑒)

   

BDV = PCLK/(BR)

UART2BDR = BDV
