2-4. Manual Configuration Mode
When OPL3-SA3 is in the Wait for Key state, it can be changed to the Manual Configuration mode
by sending the following YAMAHA key to Address_Port. The Manual Configuration mode is used
for downloading the resource data to EEPROM and internal SRAM, setting up the OPL3-SA3
without PnP protocol.
YAMAHA Key:
B1h, D8h, 6Ch, 36h, 9Bh, 4Dh, A6h, D3h,
69h, B4h, 5Ah, ADh, D6h, EBh, 75h, BAh,
DDh, EEh, F7h, 7Bh, 3Dh, 9Eh, CFh, 67h,
33h, 19h, 8Ch, 46h, A3h, 51h, A8h, 54h
In the Manual Configuration mode, PnP registers can be accessed by the host without PnP protocol.
Right after OPL3-SA3 is switched to the Manual Configuration mode, set “81h” in CSN register
automatically to put OPL3-SA3 in ‘Sleep’ State. And when “81h” is written to Wake [CSN], it
becomes possible to access to Configuration register of each logical device from the host.
To return from the Manual Configuration mode to PnP auto-configuration mode, the Wait for Key
command should be sent.
Note :
The Manual Configuration mode can not be used in the system with more than one OPL3-SA3’s card
installed in the ISA slot.
