ECLK -

SCLKB6

E

21MHz Clock supplied by the Engine. Data is accepted by the Controller at this CLK
transitions to true. This CLK sends to Engine as the CCLK. This ECLK is transmitted
from the Engine to the Controller. Then, ECLK is generated into CCLK at the
Controller and transmitted to the Engine. This signal is always output during
power-on.

CCLK

BPCLK

C

21MHz Clock supplied by the Controller. Data is accepted by Engine at this CLK
transitions to true. This signal is always output during power-on.
