put latches. In the default condition, VFBLANK is low to
enable its VFD tube driver outputs to follow the state of
the VFD tube driver’s output latches. The VFBLANK out-
put is used for PWM intensity control and to disable the
VFD tube driver in shutdown.
Multiplex Architecture
The multiplex engine transmits grid and anode control
data to the external VFD driver using VFCLK, VFDOUT,
and VFLOAD. The number of data bits m transmitted is
set by the user in the shift-limit register (Table 30). Figure
12 is the VFD multiplex timing diagram.
The essential rules for multiplex action are as follows:
The external VFD driver’s data latch contains the
data for the current grid being displayed.
The VFBLANK input is controlled to provide the
PWM intensity control.
The VFCLK and VFDOUT outputs are used to fill the
external VFD driver’s shift register with the multiplex
data for the next grid, during the multiplex timeslot
for the current grid.
The VFLOAD output loads the new grid-anode data
pattern at the start of its multiplex cycle.
