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.
The signals output by $0X to $3X in the table above cannot be read out during the auto sequence operation.
Description of SENS Signals
SENS output
XBUSY
Contents
Low while the auto sequencer is in operation, high when operation terminates.
Outputs the same signal as the FOK pin.
High for "focus OK".
FOK
GFS
High when the regenerated frame sync is obtained with the correct timing.
COUT
frequency
division
Counts the number of tracks with frequency division ratio set by $B.
High when $B 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.
