POWER-UP RESET
In order to facilitate state machine design and testing, a power-up
reset function has been incorporated in the PLC18V8Z. All internal
registers will reset to Active-Low (logical “0”) after a specified period
of time (t
PPR
). Therefore, any OMC that has been configured as a
registered output will always produce an Active-High on the
associated output pin because of the inverted output buffer. The
internal feedback (Q) of a registered OMC will also be set Low. The
programmed polarity of OMC will not affect the Active-High output
condition during a system power-up condition.
