/* Blocking mode */

int FLEXCOMx_USART_ReadByte( void )

Summary

Submits request to read a byte of data to the given USART peripheral

Description

This function submits request to read a byte of data to the given USART peripheral. This Function is available only in blocking mode. Application must call the FLEXCOMx_USART_ReceiverIsReady API to check if a byte is available with the receiver before calling this API.

Precondition

  • FLEXCOMx_USART_Initialize must have been called for the associated USART instance.

  • Receiver readiness must be confirmed using FLEXCOMx_USART_ReceiverIsReady.

Parameters

None

Returns

Read byte.

Example 

char rxData;

if(FLEXCOM0_USART_ReceiverIsReady() == true)
{
    rxData = FLEXCOM0_USART_ReadByte();
}

Remarks

None
