LPC1347 watchdog problem

Hello,

I have the following problem with the watchdog feature of the LPC1347.
When I program the WDMOD register with 0x0023, all works as expected.
But when I set it to 0x0033 (with the WDPROTECT bit active), the watchdog does not react to a hangup test at all.  As I understand, WDPROTECT protects the TC register against unintentional changes, but the TC register was already set befóre writing WDMOD. Any help or suggestions would be fabulous.

Marcus.
