Fix sending
Add Tx abort and SSC reset functionalities
There is a bug workaround for a peculiarity in the SSC Tx: When it is set to START CONTINOUS while a transmission is in progress (started by START TF RISING EDGE, which is necessary for the correct
timing) it will lose one (or two?) bits of sample data. The resetting of the start condition itself is necessary because the SSC will only transmit up to 64 bytes (32 bit times 16) per start
condition
Add performance counters for sent and received frames
