C
/* x = SERCOM instance number */
/* Blocking mode */
int SERCOMx_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 SERCOMx_USART_ReceiverIsReady API to check if a byte is available with the receiver before calling this API.
Precondition
SERCOMx_USART_Initialize must have been called for the associated USART instance.
Parameters
None
Returns
Read byte.
Example
//Example to use in non-interrupt char rxData; if(SERCOM0_USART_ReceiverIsReady() == true) { rxData = SERCOM0_USART_ReadByte(); }
Remarks
None
