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.
