Automatic and On-Demand Commands
Various alarms can be transmitted either automatically as a result of various alarm conditions or on demand. After
reset, all automatic transmissions are disabled. The user can enable the automatic or on-demand actions by set-
ting the proper bits in the automatic and on-demand action registers as identified below in Table 36. Table 37 shows
the programmable automatically transmitted signals and the triggering mechanisms for each. Table 37 shows the
on-demand commands.
