Cursor Setup Command
This command is used to specify the on/off state of cursor segments (SEGn-36) in the display.
The cursor outputs are issued inversely to allow an external PNP transistor to be used in
applications requiring high current drive capability. Therefore, a logic high, l, in a given bit
position will turn on the associated cursor. In applications requiring low current (less than 15
mA) drive capability, the cursor outputs may drive the VF display tube directly. In these
applications, setting to "0" turns on the cursor.

Keyscan Data Output Command
This command is used to read keyscan data via the SPI interface and has no effect on the operation
or state of the display portion of the MSC7170-01. Upon completion of this command the
KBINT
output is reset to its non-active state and the keyscan function is stopped. All bytes after Byte 1
are ignored.

NULL Command
This command has the same function as the Keyscan Data Output command with the exception
that
KBINT
is not reset and the keyscan function continues to scan the key matrix. The keyscan
may stop momentarily to prevent changing data while data output is in progress. All bytes after
Byte 1 are ignored.
