Register Format 59
Power-up DO Setup/Read Back Register
After the system powers up, the PCI-7444 can enter the initial pro-
cedure which sends out the default initial value to 128-CH digital
outputs. You can configure the default power-up DO values and
store them in the flash memory to prevent the DO from entering an
unknown status when the system turns on.
You may set the 128-CH power-up default DO values by access-
ing the Power-up DO Setup Registers in turn. After accessing the
latest Power-up DO Setup Register (Base+0x24h), the card
needs at least 500 ms to finish the writing to the flash memory pro-
cedure. You may check if the procedure is finished or not by the
nAction_Ready flag.
