Exit from power-down by either reset or external interrupt does not affect the internal

RAM content.

Note:

If idle mode is activated with power-down mode (IDL and PD bits set), the exit sequence

is unchanged, when execution is vectored to interrupt, PD and IDL bits are cleared and

idle mode is not entered.
