size_t FLEXCOMx_USART_ReadBufferSizeGet(void)
Summary
Returns the size of the receive ring buffer
Description
This function returns the size of the receive ring buffer, which is same as the size of the receive ring buffer configured in MHC.
Precondition
FLEXCOMx_USART_Initialize must have been called for the associated FLEXCOM_USART instance.
Parameters
None
Returns
The API returns the size of the receive ring buffer. If 9-bit mode is enabled, then the return value indicates the number of 9-bit data that can be copied to the internal receive ring buffer.
Example
size_t rxBufferSize; rxBufferSize = FLEXCOM0_USART_ReadBufferSizeGet();
Remarks
None
