SMBUS handle Structure definition.

HAL State structure definition.

Note: HAL SMBUS State value coding follow below described bitmap : b7-b6 Error information 00 : No Error 01 : Abort (Abort user request on going) 10 : Timeout 11 : Error b5 IP initialisation status 0 : Reset (IP not initialized) 1 : Init done (IP initialized and ready to use. HAL SMBUS Init function called) b4 (not used) x : Should be set to 0 b3 0 : Ready or Busy (No Listen mode ongoing) 1 : Listen (IP in Address Listen Mode) b2 Intrinsic process state 0 : Ready 1 : Busy (IP busy with some configuration or internal operations) b1 Rx state 0 : Ready (no Rx operation ongoing) 1 : Busy (Rx operation ongoing) b0 Tx state 0 : Ready (no Tx operation ongoing) 1 : Busy (Tx operation ongoing)

HAL Mode structure definition.

Note: HAL SMBUS Mode value coding follow below described bitmap : b7 (not used) x : Should be set to 0 b6 (not used) x : Should be set to 0 b5 0 : None 1 : Slave (HAL SMBUS communication is in Slave/Device Mode) b4 0 : None 1 : Master (HAL SMBUS communication is in Master/Host Mode) b3-b2-b1-b0 (not used) xxxx : Should be set to 0000

Enumerator
HAL_SMBUS_MODE_NONE	No SMBUS communication on going
HAL_SMBUS_MODE_MASTER	SMBUS communication is in Master Mode
HAL_SMBUS_MODE_SLAVE	SMBUS communication is in Slave Mode
