// Infinite loop
// Inside the while Loop, following operations are performed.
// 1. l_ifc_read_status is called to check the status of the LIN core.
// 2. Frame1 data is updated with the Switch status
// 3. Frame2 status is checked to find if it has been updated.
//
// 4. The bfGOTO_SLEEP in the LIN status register is checked.
//
while(1)
{
}// End of While loop
// Read LIN Core Status
// Update the switch states in Frame1
// Check if Frame2 is updated

if (TransferStatus & bfSTATUS_GOTO_SLEEP)

then the received data is processed to control the indicator lamps.
the GoToSleep function is called
BufferFrame2[0] &= ~bfLAST_TRANSACTION_OK;
ProcessFrame2();
GotoSleep();
// Clear the Last Transaction OK flag
// Process the received data
// Check if Goto Sleep flag is set
