Part I : Specification for SB Core Logic
Spec modified from ALS120 :
1. Remove all recording command.
2. No support IDE CDROM and MODEM
3. Special MPU401 mode for internal Wave Engine.
4. Remove analog block. (Substitute analog block by AC97 CODEC)
5. All SB mixer write will generate an interrupt request via MXIRQ.
6. Disable hardware power down pin.
7. Add 128 bytes RAM for special MPU401 output.
8. Remove Enhanced Game-Port.
ALS300 Power-on latch :
On power up reset ,ALS300 latch the following pin state. Their default state are :
Pin Name
MIDIOUT
Default state
Internal 50KΩ pull high
ROMCS
Internal 50KΩ pull low
After reset, pull high resistors will be disconnected from VCC and pull low resistor will disconnect
from GND. During the period of reset, the configuration register CR3 will latch those input pin state.
Please refer to CR3 definition to get details.
