DMA buffer memory in the computer Note that even when the acquired data length is less than the Data FIFO the AD data will not held in the Data FIFO but directly transferred to the host memory by bus mastering DMA The DMA transfer mode is very complex to program We recommend using a high level program library to configure this card If you want to program the software which can handle DMA bus master data transfer please refer to information about the PCI controller at www amcc com Note In DMA transfer mode the maximum acquired data length in one acquisition can be up to 64M bytes 82M samples which is the limit of the PCI controller However the memory that you allocate for data transfer must be continuous 5 2 Digital Input and Output To program the digital VO operation is fairly straightforward The digital input DI operation is to read data from its corresponding registers and the digital output DO operation is to write data to its corresponding registers The digital VO registers formats are shown in section 4 9 The DO can be read back when reading the DI port Note that the DIO data channel can only be read or written to in the form of 16 bit blocks It is impossible to access individual bits 48 e Operation Theory 5 3 General Purpose Timer Counter Operation An independent 16 bit up down timer counter is designed in the FPGA for user applications Fig 19 shows a simplified model of the timer counter on the 9116
