5.36 _9111_AD_FFHF_Polling

@ Description

This function is used to perform powerful AD data transfer by applying half-full polling mode. This method checks the FIFO half full signal every time call this function. If the FIFO is not half-full, the software do not read data. When the FIFO is full, the AD FIFO is overrun. When the FIFO is half-full but not full, software reads the A/D data, stored in FIFO, in size of one “block” (512 words). The FIFO half-full polling method is the most powerful A/D data transfer mode. Please refer to section 5.1.4 for the detailed description of half-full polling mode.
