PMC1_CPCI_INTA_STAT
-
PMC1 [CPCI Interrupt A or CPCI_BRG_P] INTA Status—
indicates the status of INTA from a PMC module installed
on PMC1. When the board is in the system slot, the
CPCI_BRG_P_INT signal is or’ed with the PMC1 INTA
signal. When the board is not in a system slot, the CPCI
INTA signal is or’ed with the PMC1 INTA signal.
0 = interrupt is de-asserted
1 = interrupt is asserted
14
PMC1_CPCI_INTB_STAT
-
PMC1/CPCI INTB Status—indicates the status of INTB
from a PMC module installed on PMC1. Each bit indi-
cates a logic or of the PMC and CPCI interrupt. When the
board is not in the system controller slot, the CPCI inter-
rupts are disabled.
0 = interrupt is de-asserted
1 = interrupt is asserted
13
PMC1_CPCI_INTC_STAT
-
PMC1/CPCI INTC Status—indicates the status of INTC
from a PMC module installed on PMC1. Each bit indi-
cates a logic or of the PMC and CPCI interrupt. When the
board is not in the system controller slot, the CPCI inter-
rupts are disabled.
0 = interrupt is de-asserted
1 = interrupt is asserted
12
PMC1_CPCI_INTD_STAT
-
PMC1/CPCI INTD Status—indicates the status of INTD
from a PMC module installed on PMC1. Each bit indi-
cates a logic or of the PMC and CPCI interrupt. When the
board is not in the system controller slot, the CPCI inter-
rupts are disabled.
0 = interrupt is de-asserted
1 = interrupt is asserted
11
PMC0_INTA_STAT
-
PMC0 INTA Status—indicates the status of INTA from a
PMC module installed on PMC0.
0 = interrupt is de-asserted
1 = interrupt is asserted
10
PMC0_INTB_STAT
-
PMC0 INTB Status—indicates the status of INTB from a
PMC module installed on PMC0.
0 = interrupt is de-asserted
1 = interrupt is asserted
9
PMC0_INTC_STAT
-
PMC0 INTC Status—indicates the status of INTC from a
PMC module installed on PMC0.
0 = interrupt is de-asserted
1 = interrupt is asserted
8
PMC0_INTD_STAT
-
PMC0 INTD Status—indicates the status of INTD from a
PMC module installed on PMC0.
0 = interrupt is de-asserted
1 = interrupt is asserted
