Drive Actions
To control the driver, you have to specify its drive state and its tristate
mode. Tristate switches are only possible at drive edges d1, d3, d4 and
d6.
Figure 108 summarizes the available drive actions.
Figure 108 Drive Actions
Any drive edge (d1 . . . d8) can switch the drive state.
Drive voltages
It can switch the driver to one of the following drive voltages:
• 1: drive high (vih)
• 0: drive low (vil)
• N: or it does not switch the driver, that is the active drive level is
retained.
Switch tristate
The drive edges d1, d3, d4 and d6 can also switch tristate:
• Z: switch tristate on
• 0: switch tristate off
• N: do not switch tristate
The drive edges d2, d5, d7, d8 require an N (F1N, F0N, N) for tristate
control because these edges cannot switch tristate.
