if this bit is set to logic 1 and EOFSOFAdjust bit (AutoTestReg
register) is logic 0, the SOF and EOF will have the maximum
length defined in ISO/IEC 14443 B.
if this bit is set to logic 1 and the EOFSOFAadjust bit is logic 1:
then
if this bit is cleared and EOFSOFAdjust bit is logic 0, the SOF
and EOF will have the minimum length defined in
ISO/IEC 14443 B.
if this bit is set to logic 0 and the EOFSOFAdjust bit is logic 1
results in an incorrect system behavior in respect to ISO
specification
SOF is suppressed
EOF is suppressed
defines EGT bit length
SOF low = (11 ETU 8 cycles) / f
SOF high = (2 ETU + 8 cycles) / f
EOF low = (11 ETU  8 cycles) / f
