◆ ll_i2c_get_slave_address()

__STATIC_INLINE uint32_t ll_i2c_get_slave_address ( i2c_regs_t *  I2Cx)

Get the slave address programmed for transfer (master mode).

Register|BitsName ---------------|--------------- TARGET_ADDR | TAR_ADDR

Parameters
I2CxI2C instance.
Return values
Valuebetween 0x0 and0x3F

Definition at line 3580 of file ll_i2c.h.

◆ ll_i2c_handle_transfer()

__STATIC_INLINE void ll_i2c_handle_transfer ( i2c_regs_t *  I2Cx,
uint32_t  slave_addr,
uint32_t  slave_addr_size 
)

Handles I2Cx communication when starting transfer or during transfer (TC or TCR flag are set).

Note
The register IC_CON and IC_TAR can only be programmed when the I2C is disabled (ENABLE = 0).

Register|BitsName ---------------|--------------- TARGET_ADDR | TAR_ADDR CTRL | CON_10BITADDR_MST

Parameters
I2CxI2C instance.
slave_addrSpecifies the slave address to be programmed.
slave_addr_sizeThis parameter can be one of the following values:
Note
SlaveAddrSize in IC_CON register can only be programmed when the I2C is disabled (IC_ENABLE = 0).
Return values
None.
