/**
* @brief HAL UART State structures definition
+ * @note HAL UART State value is a combination of 2 different substates: gState and RxState.
+ * - gState contains UART state information related to global Handle management
+ * and also information related to Tx operations.
+ * gState value coding follow below described bitmap :
+ * b7-b6 Error information
+ * 00 : No Error
+ * 01 : (Not Used)
+ * 10 : Timeout
+ * 11 : Error
+ * b5 IP initilisation status
+ * 0 : Reset (IP not initialized)
+ * 1 : Init done (IP not initialized. HAL UART Init function already called)
+ * b4-b3 (not used)
+ * xx : Should be set to 00
+ * b2 Intrinsic process state
+ * 0 : Ready
+ * 1 : Busy (IP busy with some configuration or internal operations)
+ * b1 (not used)
+ * x : Should be set to 0
+ * b0 Tx state
+ * 0 : Ready (no Tx operation ongoing)
+ * 1 : Busy (Tx operation ongoing)
+ * - RxState contains information related to Rx operations.
+ * RxState value coding follow below described bitmap :
+ * b7-b6 (not used)
+ * xx : Should be set to 00
+ * b5 IP initilisation status
+ * 0 : Reset (IP not initialized)
+ * 1 : Init done (IP not initialized)
+ * b4-b2 (not used)
+ * xxx : Should be set to 000
+ * b1 Rx state
