Input/
Output
System Address. SA[16:0] provides the 17 least significant address
bits for memory accesses and SA[15:0] provides the entire 16
address bits for I/O accesses.
MASTER#
REFRESH#
Input
ISA Master. Master control signal from the ISA bus.
ISA DRAM Refresh Control. This pin is an open drain output and
allows other masters to initiate refresh requests.
Memory Read. Acts as an output during PCI master and DMA
cycles and as an input during ISA master cycles.
Memory Write. Acts as an output during PCI master and DMA
cycles and as an input during ISA master cycles.
