Description
Output
This multi-function pin functions as ISA Reset when the
W83C553F is in PowerPC mode, as determined by pin 8 strapping
after power-up. It is driven for one millisecond duration after one of
the following conditions:
- PWRGD active edge
- Hot Reset bit set (port 92, bit 0)
- Reset Drive bit set (Clock Divisor Register bit 3)
ISA Reset is the inverted logical equivalent of PCI Reset.
When the W83C553F is in x86 mode, this pin functions as Power
Management Active. It is the output signal to the CPU bridge
which indicates the system activity status by becoming active when
a break event has occurred. Break events are programmed into PCI
Configuration Registers index 60h - 63h.
