Detailed Description

HAL State structure definition.

Note: HAL FMPI2C 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 Peripheral initialization status
0 : Reset (peripheral not initialized)
1 : Init done (peripheral initialized and ready to use. HAL FMPI2C Init function called)
b4 (not used)
x : Should be set to 0
b3
0 : Ready or Busy (No Listen mode ongoing)
1 : Listen (peripheral in Address Listen Mode)
b2 Intrinsic process state
0 : Ready
1 : Busy (peripheral 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)
