Chapter 5: Programming Examples 4-3
User’s Manual Pub. 0300266-04 Rev. A
A detailed explanation appears in the following table:
Table 4-1. Input Channel Configuration Word (O:e.0 through O:e.3)
Input Channel Enable (configuration bit 0)
Use this bit to enable or disable a channel. To minimize update times, disable any
unused channels.
When you set the channel enable bit to one, the module reads the configuration
word. Before accepting any new data as valid, verify that the status word
(described in the last subsection of this chapter) reflects the changes you made.
While the channel enable bit is set to zero, the channel data word and status word
are also set to zero. When you reset the channel enable bit to one, the channel
data word remains set to zero until your module updates the channel status word.
