in tc_fdt (thereby taking the phase information from tc_fdt, resetting the phase in tc_cdiv)
Still too much jitter (some bug in this code?)

first transfer of subsequent transmissions (32 sample-bits, equalling 2 data-bits) gets lost. It does work if I just give
the same TX buffer to the PDC twice (once after starting the TX PDC).

Switch SSC IRQ handling from edge triggered to level triggered. Somehow I was losing the ENDTX interrupt otherwise
Modified ISO14443 code for testing to enable repeated REQA->ATQA cycles. Somehow only the first ATQA is correct, subsequent ATQAs are missing the first two bits. Need to debug

* Found the problem that when switching between receiving and sending tc_cdiv would most of the time not generate an SSC_CLOCK for approx. 5ms: The issue is that after setting the divisor (which
stored in RC) CV might be greater than RC. Thus no compare will happen until CV overflows (at 0xffff carrier cycles) and therefore the clock will appear to be stopped for that time. A good fix would
have been TC_CV = TC_CV % TC_RC but unfortunately TC_CV is read-only. Instead use SWTRG to reset TC_CV to zero and then try to use the phase-shift code to have the phase stay correct.
* Measured the transmit start delay that is introduced by the SSC TF emulation through FIQ and adjusted ISO14443A_FDT accordingly

added during the last week)
Change freertos code to not mask FIQ, this finally makes the FIQ working (with approx 700ns +/- 100ns latency; yeah!) and therefore reception starts working
Change to two times oversampling (keep four times oversampling code ifdef'd, extract all the magical values to a header file) because at four times oversampling every other sample is very close to
a possible data edge and therefore not reliable

continuous mode (with new short and incomplete ssc irq handler: FIXME, either switch back to original handler (maybe fixing it
if necessary) or handle the missing cases in the new handler). Lots of debug statements still in there

Almost all of these have not been checked yet, I just copied them over and hot-fixed compile time errors
F.e. all ssc usb code has been removed
