Notes) • PCMD is a MSB first, two's complement output.

• GTOP is used to monitor the frame sync protection status. (High: sync protection window opens.)

• XUGF is the frame sync obtained from the EFM signal, and is negative pulse. It is the signal before

sync protection.

• XPCK is the inverse of the EFM PLL clock. The PLL is designed so that the falling edge and the EFM signal transition point coincide.

• The GFS signal goes high when the frame sync and the insertion protection timing match.

• RFCK is derived from the crystal accuracy, and has a cycle of 136µs.

• C2PO represents the data error status.

• XROF is generated when the 16K RAM exceeds the ±4F jitter margin.

§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.

The meaning of the data for each address is explained below.

$4X commands

RXF = 0 FORWARD RXF = 1 REVERSE

• When the Focus-on command ($47) is canceled, $02 is sent and the auto sequence is interrupted.

• When the Track jump/Move commands ($48 to $4F) are canceled, $25 is sent and the auto sequence is

interrupted.

$5X commands

Auto sequence timer setting Set timers: A, E, C, B

e.g.) D2 = D0 = 1, D3 = D1 = 0 (Initial Reset)

A = E = C = 0.11ms B = 0.23ms

$6X commands

Auto sequence timer setting Set timer: D

e.g.) D3 = 0, D2 = D1 = D0 = 1 (Initial Reset)

D = 10.15ms

$7X commands

Auto sequence track jump/move count setting (N)

This command is used to set N when a 2N-track jump or N-track move is executed for auto sequence.

• The maximum track count is 65,535, but note that with a 2N-track jump the maximum track jump count depends on the mechanical limitations of the optical system.

• The number of tracks jumped is counted according to the COUT signals.
