3.4.33 Power-down configuration register
Table 36.
The bits in the PDRUNCFG register control the power to the various analog blocks. This
register can be written to at any time while the chip is running, and a write will take effect
immediately with the exception of the power-down signal to the IRC.
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.
By default, the IRC and flash memory are powered and running and the BOD circuit is
enabled.
Remark: Reserved bits must be always written as indicated.
