Hi allAs shown in the figure below, RIA, FRZ, etc. in the SWT_CR register can be changed, but only WEN can't be set to 1. I'd like to know what's the reason for this, thanks! 

hi，I am unable to enable the swt2 watchdog, I have set wen to 1, also I have RIA to 0 in my registers, does this issue have any effect, also I have a problem with my SR registers not displaying, I would appreciate an answer, thanks.
