5.9 _9111_EDO
@ Description
There are 4 extended digital output channels on the PCI_9111. This
function is used to write data to the extended digital output port. The
extended digital output channels can be set with 3 different modes (refer
to chapter 4); however, the output EDO value can only be place on the
EDO pins when the EDO mode is set as EDO_OUT_CHN. Therefore, the
program must call the _9111_Set_EDO_Function function (refer to
chapter 4) to set the EDO mode as EDO_OUT_EDO before writing data
to the EDO channels.
