Register initialization files (read/write)
Register initialization from address 10h to address 2Fh is performed automatically during
the initializing phase (see
Section 9.7.3 on page 28
) using the StartUp register
initialization file.
In addition, the MFRC531 registers can be initialized using values from the register
initialization file when the LoadConfig command is executed (see
Section 11.4.1 on
page 86
).

maximum source resistance for the
p-channel driver transistor on pins TX1 and
TX2
The source resistance of the p-channel
driver transistors of pin TX1 and TX2 can be
adjusted using the value GsCfgCW[5:0] in
the CwConductance register (see
Section 9.9.3 on page 30
). The mean value
of the maximum adjustable source
resistance for pins TX1 and TX2 is stored
as an integer value in
Ω
in this byte. Typical
values for RsMaxP are between 60
Ω
to
140
Ω
. This value is denoted as maximum
adjustable source resistance R
S(ref)maxP
and
is measured by setting the CwConductance
register’s GsCfgCW[5:0] bits to 01h.
