Subject: [PATCH, FT32] sim: correctly simulate PM write port
Date: Mon, 28 Sep 2015 23:50:00 -0000	[thread overview]
Message-ID: <CA9BBF0458F83C4F9051448B941B57D11961FBDD@glaexch3> (raw)

The FT32 simulator was not correctly simulating the behavior of the
program memory (PM) write port.  This patch fixes it.

OK to apply?
