Document Table of Contents The WAY Field

The WAY field controls the mapping from the VPN to a particular TLB entry. WAY specifies the set to be written to in the TLB. The MMU increments WAY when system software performs a TLB write operation. Unused upper bits in WAY must be written as zero.
Note: The number of ways (sets) is configurable in Platform Designer at generation time, up to a maximum of 16.
