Bit 15 is strobe 2 and bit 14 is strobe 1. A logical OR is taken between the two
leftmost bits of the command code and bits 15 and 14, and the result is
attached as the strobe to the operation command. The command code for
K3HB-DRT operation commands is 0@ hex, so when the logical OR is 8@
hex, the strobe is ON.
Resetting with an operation command is used for the following example.
