# The RAM+flash MCP in the GTA02 GSM modem block is SEC K5A3281CTM.
# The closest datasheet that could be found is for K5A3280;
# all current understanding of this IC is based on the latter datasheet.

# OsmocomBB sets WS=3 for both nCS0 and nCS1.  At first I was concerned that
# the setting was wrong for nCS0, but I have now located the responsible
# code in the moko11 binary (see the moko11 notes file in the
# freecalypso-reveng Hg tree) and confirmed that the official firmware
# runs with the same settings.  So let's do likewise.
