MODE

RRAM standby mode

Normal

0

The RRAM automatically goes into idle mode while the RRAM is not being accessed

The MCU power domain is turned off.

PowerDown

2

The RRAM goes into power down mode when the access timeout counter is expired

The penalty for RRAM access during wakeup from PowerDown mode is about 6us

Standby

3

The RRAM remains active while the RRAM is not being accessed.

Access to RRAM has the lowest latency when MCU PD is in RUN state, for example by using Constant Latency sub-power mode. ACCESSTIMEOUT has no effect in this mode.
