User manual
To avoid glitches when powering down the IRC, the IRC clock is automatically switched off
at a clean point. Therefore, for the IRC a delay is possible before the power-down state
takes effect.
Remark: Settings in this register are affected by the WDT lock status:

If the watchdog oscillator is selected as the clock source for the WDT, writes to bit 6 in
the PDRUNCFG register are ignored if at the same time bit 5 is set in the MOD
register (see
If the IRC is selected as the clock source for the WDT, writes to bits 0 and bit 1 in the
PDRUNCFG register are ignored if at the same time bit 5 is set in the MOD register
