WIDTH denotes the physical memory attributes for a bus transaction in
conjunction with WIDTH/HLTD1/RETRY:
WIDTH/HLTD1/RETRY WIDTH/HLTD0
WIDTH/HLTD0 For proper operation, do not connect this signal to ground.
This signal has a weak internal pullup which is active during reset to ensure
normal operation.
HLTD0 signal name has no function in the 80960RX; the signal name is
included for 80960JF naming convention compatibility.
WIDTH denotes the physical memory attributes for a bus transaction in
conjunction with the WIDTH/HLTD0 signal. Refer to description above.
RETRY is sampled at Primary PCI bus reset to determine when the Primary
PCI interface is disabled. When high, the Primary PCI interface disables PCI
configuration cycles by signaling a RETRY until the Extended Bridge Control
Register Configuration Cycle Disable bit is cleared. When low, the Primary
PCI interface allows configuration cycles to occur. WIDTH/HLTD1/RETRY
has a weak internal pullup which is active during reset to ensure normal
operation when the signal is not connected.
HLTD1 signal name has no function in the 80960RX; the signal name is
included for 80960JF naming convention compatibility.
