henryk 2bf5a3ae4e 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
