126 * and also information related to Tx operations.
127 * gState value coding follow below described bitmap :
129 * x : Should be set to 0
130 * b6 Error information
133 * b5 CEC peripheral initialization status
134 * 0 : Reset (peripheral not initialized)
135 * 1 : Init done (peripheral initialized. HAL CEC Init function already called)
137 * xx : Should be set to 00
138 * b2 Intrinsic process state
140 * 1 : Busy (peripheral busy with some configuration or internal operations)
142 * x : Should be set to 0
144 * 0 : Ready (no Tx operation ongoing)
145 * 1 : Busy (Tx operation ongoing)
146 * - RxState contains information related to Rx operations.
147 * RxState value coding follow below described bitmap :
149 * xx : Should be set to 00
150 * b5 CEC peripheral initialization status
151 * 0 : Reset (peripheral not initialized)
