## Summary
+ Fix EtherCAT signals drive strengh (from errata PORTS_CM.H002) in
_**xmc4_pinmux.h**_,
-> STRONG SHARP signal caused high EMI which lead to MCU bus faults.
-> Switch to STRONG SOFT according to Infineon's recommendations.
+ Changed _**xmc4_ecat.c**_ for compile time pin definition.
+ Fixed **_xmc4_ecat.c_** Ethercat common port config register not written
(reset value already used).
- Disabled EXTCLK pin for xmc4800 as pin is used for ECAT Run LED later.
+ Clean xmc4 familly board.h and clocks config.
## Impact
- Signal strength change removed occurrences of MCU Bus Fault on PCB where
ECAT traces were going under the MCU.
- EXTCLK pin is disabled on xmc48 board.h, as it is overridden by ECAT Run
LED later when EtherCAT is enabled (EtherCAT is basically the purpose of
XMC4800)
- EXTCLK is now setup only if BOARD_EXTCKL_ENABLE == 1 in board.h
- Other changes brings no impact on current boards.
## Testing
All xmc45, xmc47 and xmc48 nsh example compiled correctly.
Tested on a custom xmc48 board using EtherCAT.
