The module has two basic modes of opera- tion. Any or all of-these features may be enabled. The user parameter memory can be accessed. The parameter memory contains the threshold and pedestal data for each channel and occu- pies 96 bytes of CSR space. The LIFO is organized as 1024 32-bit words.
Data is stored two channels per word, with a header word per event.
Thus, the LIFO capacity is 1024 null events or 60 events of 32 channels of data each. The LIFO may be read out in either random or in block mode. The entire buffer may be reread if desired. Partial reads of the LIFO should be avoided.
