Description
Shows the status of the internal testbus. The testbus is selected by the
register TestSel2Reg. See
AmpRcv
Description
Reserved for production tests.
If set to logic 1, the internal signal processing in the receiver chain is
performed non-linear. This increases the operating distance in
communication modes at 106 kbit.
Note: Due to the non linearity the effect of the bits MinLevel and
CollLevel in the register RxThreshholdReg are as well non linear.
Reserved for future use.
Maximum length of SOF and EOF according to ISO/IEC14443B
If set to logic 0 and the EOFSOFwidth is set to 0 will result in the
Minimum length of SOF and EOF according to ISO/IEC14443B
If this bit is set to 1 and the EOFSOFwidth bit is logic 1 will result in
SOF low = (11 etu − 8 cycles)/fc
SOF high = (2 etu + 8 cycles)/fc
EOF low = (11 etu − 8 cycles)/fc
Enables the digital self test. The selftest can be started by the selftest
command in the command register. The selftest is enabled by 1001.
Note: For default operation the selftest has to be disabled by 0000.
