Chip Select Waveforms
All these chip select signals appear at power ON. The first five chip se-
lect signals also appear as long as the unit is ON. The last two only
appear at power ON and during the PB of a disc (or when the disc is
paused).
All waveforms are 3.3Vp-p taken at 10usec/div. time base.
