REGISTER PRELOAD FUNCTION
(DIAGNOSTIC MODE ONLY)
In order to facilitate the testing of state machine/controller designs, a
diagnostic mode register preload feature has been incorporated into
the PLC18V8Z series device. This feature enables the user to load
the registers with predetermined states while a super voltage is
applied to Pins 11 and 6 (I9/OE and I5). (See diagram for timing and
sequence.)
To read the data out, Pins 11 and 6 must be returned to normal TTL
levels. The outputs, F0 – F7, must be enabled in order to read data
out. The Q outputs of the registers will reflect data in as input via
F0 – F7 during preload. Subsequently, the register Q output via the
feedback path will reflect the data in as input via F0 – F7.
Refer to the voltage waveform for timing and voltage references.
