The MPAMCFG_MBW_WINWD characteristics are:
MPAMCFG_MBW_WINWD is a 32-bit register that shows (and sets) the value of the window width for the PARTID in MPAMCFG_PART_SEL.
MPAMCFG_MBW_WINWD is read-only if Mext-PAMF_MBW_IDR.WINDWR == 0, and the window width is set by the hardware, even if variable.
MPAMCFG_MBW_WINWD is read-write if MPAMF_MBW_IDR.WINDWR == 1, permitting configuration of the window width for each PARTID independently on hardware that supports this functionality.
The power domain of MPAMCFG_MBW_WINWD is IMPLEMENTATION DEFINED.
This register is present only when MPAMF_IDR.HAS_MBW_PART == 1. Otherwise, direct accesses to MPAMCFG_MBW_WINWD are IMPLEMENTATION DEFINED.
MPAMCFG_MBW_WINWD is a 32-bit register.
The MPAMCFG_MBW_WINWD 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 |
0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | US_INT | US_FRAC |
Reserved, RES0.
Window width, integer microseconds.
This field reads (and sets) the integer part of the window width in microseconds for the PARTID selected by MPAMCFG_PART_SEL.
Window width, fractional microseconds.
This field reads (and sets) the fractional part of the window width in microseconds for the PARTID selected by MPAMCFG_PART_SEL.
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_MBW_WINWD must be accessible from the Non-secure and Secure address maps.
MPAMCFG_MBW_WINWD must be banked for the Secure and Non-secure address maps. The Secure instance accesses the window width used for Secure PARTIDs, and the Non-secure instance accesses the window width used for Non-secure PARTIDs.
