TRDY 196
I/O
Target ready. Indicates the PCI 1131 ability to complete the current
data phase of the transaction. TRDY is used in conjunction with IRDY.
A data phase is completed on any clock where both TRDY I/O are
sampled asserted. During a read, TRDY indicates that valid data is
present on AD31-0. During a write, TRDY indicates the PCI1131 is
prepared to accept data. Wait cycles are inserted until both TIRDY and
TRDY are asserted together. This signal is an output when the PCI
1131 is the PCI target. and an input when it is the PCI bus master.
IRQ10/CLKRUN
159
IRQ12/CLKRUN
161
I/O
Interrupt Request 10 and 12. This terminal is software configurable
and is used by the PCI 1131 to support the PCI Clock Run protocol.
When configured as CLKRUN, by setting bit 0 in the System Control
Register at offset 80h, this terminal is an open drain output. To select
between IRQ10 and IRQ12 as the output use bit 7 of Register 80h.
