§1-4. Description of SENS Signals and Commands
SENS output
The SENS output can be read from the SQSO pin when SOCT = 0, SL1 = 1 and SL0 = 0. (See $BX commands.)
$38 outputs AGOK during AGT and AGF command settings, and XAVEBSY during AVRG measurement.
SSTP is output in all other cases.

Description of SENS Signals
Low while the auto sequencer is in operation, high when operation terminates.
Outputs the same signal as the FOK pin.
High for "focus OK".
High when the regenerated frame sync is obtained with the correct timing.
Counts the number of tracks with frequency division ratio set by $B.
High when $C is latched, and toggles each time COUT is counted just for the frequency
division ratio set by $B.
Low when the EFM signal is lengthened by 64 channel clock pulses or more after passing
through the sync detection filter.
