Default :
After initial clear, all the bits of Register Array 1 are cleared to "0" except NEW2 and NEW3 bits of
index 05h, and CHA and CHB bits of index C0-C8h.
For the details of these registers, refer to data sheet for YMF289B(OPL3-L).
Note :
Since NEW2 and 3 (at index 05h of Register array1) = 1 in default state, both LD and BUSY0 bits
are valid. (LD and BUSY0 bits are invalid when NEW2=0.) BUSY0 is a BUSY flag for both FM
and Wavetable registers.
