ENGR00115329 Enable NFC symmetric mode on MX51
Enable NFC symmetric mode on MX51. MX51TO2 NFC
working has somelimitation, refer to ENGcm09121.
NFC symmetric mode should be used as for the NFC
clock is 33M vs AXI clock is 133M. The ratio is
1:4, according to ENGcm09121, only NFC symmetric
mode can work, asymmetric mode does not work.
