Detailed Description

Enumeration Type Documentation

HAL Mode structure definition.

Note: HAL I2C Mode value coding follow below described bitmap : b7 (not used) x : Should be set to 0 b6 0 : None 1 : Memory (HAL I2C communication is in Memory Mode) b5 0 : None 1 : Slave (HAL I2C communication is in Slave Mode) b4 0 : None 1 : Master (HAL I2C communication is in Master Mode) b3-b2-b1-b0 (not used) xxxx : Should be set to 0000

Enumerator
HAL_I2C_MODE_NONE	No I2C communication on going
HAL_I2C_MODE_MASTER	I2C communication is in Master Mode
HAL_I2C_MODE_SLAVE	I2C communication is in Slave Mode
HAL_I2C_MODE_MEM	I2C communication is in Memory Mode
