Recall Mode Byte

The Mode byte allows an E-MEM recall with Effects Dissolve, Auto Recall,
and Run, either separately or together. The Mode byte takes precedence
over the Switcher button tallies. The mode byte looks at four operations:

Force the Run/Auto Recall/Effects Dissolve/Sequence operation

Inhibit the Run/Auto Recall/Effects Dissolve/Sequence operation

Operate according to current Switcher panel settings

The format of the Recall Mode byte is provided in

Table 69

.

Effects Dissolve, Sequence, Auto Recall, and Run each have a Force bit and
an Inhibit bit. If the Force bit is on, the action is performed irrespective of
the state of the switcher. If the Inhibit bit is on, the action is not performed,
irrespective of the state of the switcher. If both bits are off, then the action
is performed according to the switcher state, that is, what has been recalled
from E-MEM, modified by the current state of the panel. (Refer to

Table 70

.)

Setting Bit 5 to one recalls an E-MEM register and runs any keyframes
stored in that register. This has the same effect as pushing the AUTO RUN
pushbutton and then recalling an E-MEM register from the control panel.
Setting Bit 1 to one recalls an E-MEM which does not run, irrespective of
the state of the AUTO RUN button. If both Bits 5 and 1 are set to zero, then
the E-MEM is recalled and will run only if the AUTO RUN button is on.
