Description:
Comparator Mask registers
Address:
0xE0001034
Offset:
0x34
Retention:
Retained
IsDeepSleep:
No
Comment:
The MASKn register characteristics are:
Purpose: Provides the size of the ignore mask applied to the access address for address
range matching by comparator n.
Usage constraints: The operation of comparator n depends also on the registers COMPn and
FUNCTIONn, see Comparator registers, COMPn and Comparator Function registers,
FUNCTIONn on Arm TRM page C1-806.
Configurations:
Implemented only when CTRL.NUMCOMP is nonzero, see Control register, CTRL on Arm
TRM page C1-797.
CTRL.NUMCOMP defines the number of implemented MASKn registers. Implemented
MASKn registers number from 0 to (NUMCOMP-1). Unimplemented registers are UNK/SBZP.
Attributes: See Table C1-21 on Arm TRM page C1-797.
Default:
0x0

Description
0:4 MASK RW R 0 The size of the ignore mask, 0-31 bits, applied to
address range matching.
The maximum mask size is IMPLEMENTATION
DEFINED. A debugger can write 0b11111 to this field
and then read the register back to determine the
maximum mask size supported.
