SRCN [23:16] rh PCP Node m Service Request Channel Number
Channel Number Entry (default = 0). When the PCP
interrupt request was raised by the PCP Processor
Core when executing an EXIT instruction, then this
bit field contains the SRPN value taken from R6
when the exit instruction was executed. When the
PCP interrupt request was raised by the PCP
Processor Core when suspending execution of a
channel program in order to service a higher-priority
interrupt then this bit field contains the channel
number of the channel that was suspended.
RES [15:14] r Reserved
Read as 0.
SRR 13 rh PCP Node m Service Request Flag
0
B
No service requested (default)
1
B
Valid active service requested
SRE 12 r PCP Node m Service Request Enable
Always read as 1 (enabled).
TOS [11:10] r PCP Node m Type-of-Service State
Always read as 01
B
. This means TOS is associated
with interrupt bus 1 (PCP interrupt arbitration bus).
RES [9:8] r Reserved
Read as 0.
SRPN [7:0] rh PCP Node m Service Request Priority Number
This number is automatically set by the PCP if it
needs to place a service request on interrupt bus 0
(CPU interrupt arbitration bus) or 1 (PCP interrupt
arbitration bus).
When the PCP interrupt request contained was
raised by the PCP Processor Core when executing
an EXIT instruction then this bit field contains the
SRPN value taken from R6 when the exit instruction
was executed. When the PCP interrupt request was
raised by the PCP Processor Core when suspending
execution of a channel program in order to service a
higher-priority interrupt then this bit field contains the
CPPN value of the PCP when the interrupt was
suspended.
