The MPAMF_CCAP_IDR characteristics are:
Indicates the number of fractional bits in MPAMCFG_CMAX for this MSC. MPAMF_CCAP_IDR_s indicates the number of fractional bits in the Secure instance of MPAMCFG_CMAX. MPAMF_CCAP_IDR_ns indicates the number of fractional bits in the Non-secure instance of MPAMCFG_CMAX.
The power domain of MPAMF_CCAP_IDR is IMPLEMENTATION DEFINED.
This register is present only when MPAMF_IDR.HAS_CCAP_PART == 1. Otherwise, direct accesses to MPAMF_CCAP_IDR are RES0.
MPAMF_CCAP_IDR is a 32-bit register.
The MPAMF_CCAP_IDR 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 | CMAX_WD |
Reserved, RES0.
Number of fractional bits implemented in the cache capacity partitioning control, MPAMCFG_CMAX.CMAX, of this device. See MPAMCFG_CMAX.
This field must contain a value from 1 to 16, inclusive.
This register is within the MPAM feature page memory frames. In a system that supports Secure and Non-secure memory maps, there must be both Secure and Non-secure MPAM feature pages.
MPAMF_CCAP_IDR is read-only.
MPAMF_CCAP_IDR must be readable from the Non-secure and Secure MPAM feature pages.
MPAMF_CCAP_IDR is permitted to have the same contents when read from either the Secure and Non-secure MPAM feature pages unless the register contents is different for Secure and Non-secure versions, when there must be separate registers in the Secure (MPAMF_CCAP_IDR_s) and Non-secure (MPAMF_CCAP_IDR_ns) MPAM feature pages.
