I2C keeps waiting for one byte transfer completion

[chunkitmax]

// Wait until data is received
while (!GET_BIT(MEM_MAPS[m_module]->S, I2C_S_IICIF_SHIFT))
{
    if (GET_BIT(MEM_MAPS[m_module]->SMB, I2C_SMB_SLTF_SHIFT))
    {
        LOG_DL("i2c scl timeout");
        return false;
    }
}

The interrupt flag in I2C status register was 0. The if statement was false.
The I2C interrupt enable flag in I2C control register 1 was found being 0.

Trying to simply set the I2C interrupt flag to 1 if it is 0 to fix this problem.
