If Auto Load is enabled the Drive will automatically
perform an operation equivalent to a LOAD/UNLOAD command
with the Load bit set to one every time a new cartridge
is inserted into the Drive.

This field specifies the delay that will be applied
before mechanical activity (head or capstan motor) is
started
after
Power-Up/Reset;
100 ms. This can be used to delay the motor current
surges after a Power-Up/Reset condition.

The default (factory programmed) value is 0.
When this bit is set the Drive will simulate the TAR
(1/2' reel-to-reel) overwrite feature.
The overwrite function can be used to overwrite data
after the first data block on the tape or to overwrite
the last of two sequential filemarks before EOD. See
section 2.5 for further details.
Legal values are 0 and 1.
The default (factory programmed) value is 0.
