Notes)

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

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

• 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. (during normal speed)

• C2PO represents the data error status.

• XROF is generated when the 32K RAM exceeds the ±28F jitter margin.

Description of SENS Signals

The SENS pin is high impedance. 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 set with Reg.B.

High when Reg.B is latched, low when the initial Reg.B number is counted through COUT. Counts the number of tracks set with Reg.B.

High when Reg.B is latched, toggles each time the Reg.B number is counted through COUT. While $44 and $45 are being executed, toggles with each COUT 8-count instead of the Reg.B number.

Low when the EFM signal is lengthened by 64 channel clock pulses or more after passing through the sync detection filter.
