The set values “nrfx_wdt_config_t”are different from the register values“NRF_WDT->CRV”

timeout [s] = ( CRV + 1 ) / 32768

Hello,

Not sure I understand what the questions is, but it's not possible to re-configure the WDT after you have started it. In that case you wait for it to time out. Also, the NRFX_WDT_CONFIG_RELOAD_VALUE corresponds to the WD timeout in milliseconds.
