Wait time extension commands are not implemented yet.
They are a nice-to-have for the future, since they would enable
the board to work with phones that expect a higher frequency.
With a wait time extension request towards the phone, SIMtrace could
signal the phone to wait for a longer time period while SIMtrace is
still waiting for a response from the SIM card.
The define PR was introduced to switch quickly between TRACE levels
for specific debug print messages.
Now, it all became debug output, since it is not needed in normal
operation.
* Sniffer uses phone endpoints for communication and the ringbuffer
routines the phone communication uses
* Most times the Usart1 interrupt is not triggered, and therefore
no values are recorded
* ISO7816_Init: Takes Usart_info and CLK_SLAVE/CLK_MASTER as param
* ISO7816_SendChar, ISO7816_GetChar: Usart_info is passed
* ISO7816_Set_Reset_Pin function for CCID part
* iso7816_4.c: BOARD_ISO7816_BASE_USART replaced by USART_SIM
* Redundant _ISO7816_Init, _ISO7816_SendChar, _ISO7816_GetChar
functions removed
* All simtrace modes use iso7816_4.c functions instead of redefined
_ISO7816_xxx functions
* Implemented configure, init, exit functions:
When a configuration is changed, interrupts for reset pins
should be disabled
* Moved variables shared between code files to simtrace.h
