Name Bit(s) Type Function
HOSEn_PWROK_TR
<3> W1C, X HOSEn Power OK Transitioned. This bit is
latched whenever the associated HOSEn_
PWROK signal transitions. HOSEn_PWROK
can then be read to determine the reason why
this bit set. A PWROK transition from 0 to 1 in-
dicates a power-up, while a PWROK transition
of 1 to 0 indicates a power-down.
The bit indicates an I/O adapter’s power transi-
tion status on a given hose "n" as follows:
HOSEn_PWROK_TR in IDPNSE3 indicates
an I/O adapter’s power transition status on
hose 3.
HOSEn_PWROK_TR in IDPNSE2 indicates
an I/O adapter’s power transition status on
hose 2.
HOSEn_PWROK_TR in IDPNSE1 indicates
an I/O adapter’s power transition status on
hose 1.
HOSEn_PWROK_TR in IDPNSE0 indicates
an I/O adapter’s power transition status on
hose 0.
An IPL 17 interrupt is generated when this bit
sets if interrupts are enabled by INTR_NSES
(ICCNSE<31>).
HOSEn_CBLOK
<2> R, X HOSEn Cable OK. This bit is derived from the
hose signal CBLOK. If the associated hose cable
is good and connected properly and the I/O
adapter is plugged into its card cage, this bit will
be a 1. The setting of this bit does not result in
any TLSB interrupt.
The bit indicates an I/O adapter’s hose cable
status on a given hose "n" as follows:
HOSEn_CBLOK in IDPNSE3 indicates an
I/O adapter’s hose cable status on hose 3.
HOSEn_CBLOK in IDPNSE2 indicates an
I/O adapter’s hose cable status on hose 2.
HOSEn_CBLOK in IDPNSE1 indicates an
I/O adapter’s hose cable status on hose 1.
HOSEn_CBLOK in IDPNSE0 indicates an
I/O adapter’s hose cable status on hose 0.
