The MPAMCFG_INTPARTID characteristics are:
MPAMCFG_INTPARTID is a 32-bit read-write register that controls the mapping of the PARTID selected by MPAMCFG_PART_SEL into a narrower internal PARTID (intPARTID).
The MPAMCFG_INTPARTID register associates the request PARTID (reqPARTID) in the MPAMCFG_PART_SEL register with an internal PARTID (intPARTID) in this register. To set that association, store reqPARTID into the MPAMCFG_PART_SEL register and then store the intPARTID into the MPAMCFG_INTPARTID register. To read the association, store reqPARTID into the MPAMCFG_PART_SEL register and then read MPAMCFG_INTPARTID.
If the intPARTID stored into MPAMCFG_INTPARTID is out-of-range or does not have the INTERNAL bit set, the association of reqPARTID to intPARTID is not written and MPAMF_ESR is set to indicate an intPARTID_Range error.
If MPAMCFG_PART_SEL.INTERNAL is 1 when MPAMCFG_INTPARTID is read or written, MPAMF_ESR is set to indicate an unexpected_internal error.
The power domain of MPAMCFG_INTPARTID is IMPLEMENTATION DEFINED.
This register is present only when MPAMF_IDR.HAS_PARTID_NRW == 1. Otherwise, direct accesses to MPAMCFG_INTPARTID are IMPLEMENTATION DEFINED.
MPAMCFG_INTPARTID is a 32-bit register.
The MPAMCFG_INTPARTID bit assignments are:
31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
RES0 | INTERNAL | INTPARTID |
Reserved, RES0.
Internal PARTID flag.
This bit must be 1 when written to the register. If written as 0, the write will not update the reqPARTID to intPARTID association.
On a read of this register, the bit will always read the value last written.
This field contains the intPARTID mapped to the reqPARTID in MPAMCFG_PART_SEL.
The maximum intPARTID supported is MPAMF_PARTID_NRW_IDR.INTPARTID_MAX.
This register is part of the MPAMF_BASE memory frame. In a system that supports Secure and Non-secure memory maps, the MPAMF_BASE frame must be accessible in both Secure and Non-secure memory address maps.
MPAMCFG_INTPARTID must be accessible from the Non-secure and Secure address maps.
MPAMCFG_INTPARTID must be banked for the Secure and Non-secure address maps. The Secure instance accesses the PARTID narrowing used for Secure PARTIDs, and the Non-secure instance accesses the PARTID narrowing used for Non-secure PARTIDs.
