HAL UART State enumerations definition.

Note
  HAL UART State value is a combination of 2 different substates: gState and RxState.

Enumerator
HAL_UART_STATE_RESET | Peripheral is not initialized. Value is allowed for gState and RxState
HAL_UART_STATE_READY | Peripheral initialized and ready for use. Value is allowed for gState and RxState
HAL_UART_STATE_BUSY | An internal process is ongoing. Value is allowed for gState only
HAL_UART_STATE_BUSY_TX | Data Transmission process is ongoing. Value is allowed for gState only
HAL_UART_STATE_BUSY_RX | Data Reception process is ongoing. Value is allowed for RxState only
HAL_UART_STATE_BUSY_TXRX | Data Transmission and Reception process is ongoing. Value is allowed for gState only
HAL_UART_STATE_TIMEOUT | Timeout state. Value is allowed for gState only
HAL_UART_STATE_ERROR | Error. Value is allowed for gState only
