3.4.2.10.2. The WE Flag

When WE = 1, a write to tlbacc writes the tlbacc register and a TLB entry. When WE = 0, a write to tlbacc only writes the tlbacc register.

Hardware sets the WE flag to one on a TLB permission violation exception, and on a TLB miss exception when status.EH = 0. When a TLB write operation writes the tlbacc register, the write operation also writes to a TLB entry when WE = 1.
