SUB .
After detecting that SBSY changes from low to high by |C991, the sub-code(P~W) can be output from
SUB output terminal by inputting 8 clocks to RCK terminal at every point where SFSY changes low to
high.

This terminal is connected to ~COM.
It is an input terminal that carries the clock signal for
data transfers.

:
This connects with microcomputer and it is an output terminal for switching data transmission mode.
it enables to transmit data from SVC to microcomputer when R/M is "L" and from microcomputer to
SVC when R/W
is "H".

This terminal is the data output terminal connected to «COM. When R/W is low, data is transfer-
red from YM7121
to «COM, according to theSCK clock input.
