4.2.4 Changing Operational Modes

If memory is allocated from the USER heap for LOG and MACRO

buffers in the Controller or Peripheral modes, and the operational mode is
changed to one of the Pass-Thru modes, this memory remains allocated and
is not available to the Pass-Thru mode. Pass-Thru modes will function as
described but will not have the full memory available to them. Upon
returning to the Controller or Peripheral mode, the LOG and MACRO buffers
will be un-modified.

4.3 Clock and Timer Functions

The Micro488/EX has a built in time of day, day of week and date clock. Most

timer features, with the exception of TIME OUT and DELAY, are directly a function of
this hardware. TIME OUT and DELAY are functions of the Micro488/EX's firmware
operating system. As a result, some time skew may be observed between these
commands with respect to the clock.

Both 12 and 24 hour time output formats are available from the clock. The

relationship between the 12 and 24 hour operations are…

24 Hour

12 Hour

Midnight
