1. 16bit Address Decode
The signal AEN* generated by decoding SA15-12 and AEN needs to be connected to the
AEN of OPL3-SA3.
2. ZV Port and OPL4-ML/ML2 I/F
ZV port is supported by using the internal DAC of OPL3-SA3 that is originally dedicated for
the use of internal OPL3.
(i) either OPL4-ML/ML2 or ZV port is active at a time and simultaneous use is not
possible.
(ii) which function the internal DAC is used for is determined by the SA3 Control
register, index 02h, VZE bit.
