AUTO-SEQUENCE
This function executes the chain of commands that execute auto-focus, track jump, and move. MLT latches the
data at time L, and ISTAT is L during auto-sequence. It output H upon.

During Blind "E" time set by register 5, FOK and

Timing Chart
Auto-focus receives the auto-focus command from the MICOM in the focus search down state and focus search
up. The SSP becomes focus servo on when FZC changes to L after the internal FOK RZC satisfy 'H', all the time
set blind 'E' (Register $5X). All the internal auto focus executes ended. And this status is sent to micom through
the ISTAT output.
