ADLINK PCI-7442 - Manual (Page 72)

60 Register Format
You need not assign a register value for the Power-Up Initial DO
All Ch. Status Read Back Start. You only need to send out the
address (BASE + 0x16h) in Read mode before reading back all
inital 128-bit channel output data. When the DO bank receives the
Start command, the flash reading procedure starts in 100 ms. You
can check if the procedure is finished by get nAction_Ready flag
status.
