I am currently considering the 100-pin R5F56216BDFP, but the WDTOVF# pin doesn't exist in the pin assignment diagram in the user's manual: hardware. I couldn't find anything in the manual that says the 100-pin CPU doesn't have WDTOVF# (doesn't output an external signal at overflow). Is it not possible to output an overflow signal using the WDT in the 100-pin version?
The 100-pin LQFP doesn't have WDTOVF#.
Therefore, it is not possible to output an overflow signal using the WDT in the R5F562N8BDFP (100-pin).
This function is available with RX62N products that have 144 or more pins.
