**WD7615 Desktop Buffer Manager <04/15/92
***Info:...
***Versions:...
***Features:
o Allows the WD7XC10 based designs to work with a generic "Super l/O"
device or with the WD76C20 and WD76C30
o Replaces majority of external "glue" logic, up to 13 devices:
- AT bus address buffers with 24 mA drive
- AT bus interrupt multiplexing, and interrupt pull ups.
- AT bus DRQ multiplexing and internal pull downs.
- Keyboard/mouse interrupt latching and clearing functions
- A20 Gate logic
- Controlling the IDE data bit 7 at address 3F7H.
o Allows implementation of a desktop system with only three external
devices
o Direct connect to AT address bus SA1 through SA19 and LA17 through
LA23 with 24 mA drive
o DAC multiplexing and RESET generation
o DRAM WE signal from WD76C10 inversion and buffering
o SMEMR and SMEMW generation with 24mA direct drive
o Divide by 2 or divide by 4 clock output
o 136-pin MQFP package
