Currently <intrins.h> only supports disabling the watchdog timer via _diswdt_() but the XC166 instruction set seems to support a new ENWDT instruction (opcode 85h ?), though info on it seems very sparse in the Infineon manuals. Anybody know why there is no _enwdt_() intrinisic ? Has anybody used ENWDT or are there problems with the instruction ? Regards, J.
