A special circuit for IRAMSTBY supply failure detection is provided. In the case of supply failure
detection, the dedicated sticky bits LVSRS in the VSRMCR register are asserted. Software can read or
clear these bits. The user should enable the detector and then clear these bits. If any of the LVSR bits are
read as one, then a power failure of IRAMSTBY has occurred. The circuit is capable of detecting supply
failure below a voltage level to be determined. Also, enable/disable control bit for the IRAMSTBY
detector may be used to disconnect the circuit and save the detector power consumption.

operation. Note that for each of the conditions detailing the voltage relationships the absolute bounds of
the minimum and maximum voltage supply cannot be violated; that is, the value of VDDL cannot fall
below 2.5 V or exceed 2.7 V, and the value of VDDH cannot fall below 4.75 V or exceed 5.25 V for normal
operation. Power consumption during power up sequencing will be below the operating power
consumption.
