MaskMapping

case class MaskMapping(base: BigInt, mask: BigInt) extends AddressMapping with Product with Serializable

Creates an address mapping using a bit mask.

MaskMapping(0x0000, 0x8000) => matches 0x0000-0x8000 MaskMapping(0x40, 0xF0) => matches 0x40 - 0x4F

base

Address offset to use. Must be inside the mask

mask

Bit mask applied to the address before the check
