Master clock frequency-divider output. Selects and outputs XTAI × 1, × 1/2,
× 1/4 or low only.
7 SQCK
I
SQSO readout clock input.
8 SQSO O 1, 0 Sub Q 80-bit serial output.
9 SENS
O 1, 0 SENS output to CPU.
10 DATA
I
Serial data input from CPU.
11 XLAT
I
Latch input from CPU. Serial data is latched at the falling edge.
12 CLOK
I
Serial data transfer clock input from CPU.
13 SEIN
I
SENS input from SSP.
14 CNIN
I
Track jump count signal input.
15 DATO O 1, 0 Serial data output to SSP.
16 XLTO
O 1, 0 Serial data latch output to SSP. Latched at the falling edge.
17 CLKO
O 1, 0 Serial data transfer clock output to SSP.
18 SPOA
I
Microcomputer extended interface (input A).
19 SPOB
I
Microcomputer extended interface (input B).
20 SPOC
I
Microcomputer extended interface (input C).
21 SPOD

Used for SENS output and the servo auto sequencer.
24 VDD
— — Power supply (+5V).
25 VSS
— — GND.
26 MON
O 1, 0 Spindle motor on/off control output.
27 MDP
O 1, Z, 0 Spindle motor servo control.
28 MDS

GFS is sampled at 460Hz; when GFS is high, this pin outputs a high signal.
If GFS is low eight consecutive samples, this pin outputs low.
30 PWMI
I
Spindle motor external control input.
31 TES0
I
TEST pin; normally GND.
32 TES1
I
TEST pin; normally GND.
33 VPCO2
O
