Initialize the sequencer for run
mode. Same functionality as
Rungs 2:0 and 2:1.
Rung 2:6
This is the main block transfer
sequencer. The sequencer
output word, N9:0, is updated
whenever the previous block
transfer is done or fails. After
each sequencer increment, the
block transfer preparation
subroutine is called.
Rung 2:7
Voltage/current BTR.
