This routine is used to maintain the driver's internal transmitter state machine.This routine is called when the state of the
transmitter needs to be maintained in a polled manner.
Preconditions
DRV_UART2_InitializerDefault function should have been called before calling this function in a polled loop.
Example
Refer to DRV_UART2_InitializerDefault() for an example
Function
void DRV_UART2_TasksTX ( void );
1.2.3.3.9 DRV_UART3_InitializerDefault Function
Initializes the UART instance : 3
File
