Device Manager I2C#

Overview#

The Device Manager I2C component defines the macros, structures, and enums that are used commonly across I2C driver and peripheral.

Enumerations#

enum
sl_i2c_operating_mode_t {
SL_I2C_LEADER_MODE = 0
SL_I2C_FOLLOWER_MODE
}

Leader or Follower mode selection enum.

enum
sl_i2c_clock_hlr_t {
SL_I2C_CLK_HLR_STANDARD = 0
SL_I2C_CLK_HLR_ASYMMETRIC
SL_I2C_CLK_HLR_FAST
}

FIFO Threshold enum.

Macros#

#define
SL_I2C_OPERATING_MODE_IS_VALID (operating_mode)

Validation of operating mode.

#define
SL_I2C_FREQ_MODE_IS_VALID (freq_mode)
