1 _{Monitors VDDA, active only in Full Performance Mode. Indicates I/O & ADC performance degradation due to low supply}
voltage.
2 _{Device functionality is guaranteed on power down to the LVR assert level}
3 _{Monitors VDDX, active only in Full Performance Mode. MCU is monitored by the POR in RPM (see Figure A-5)}
4 _{The ACLK Trimming CPMUACLKTR[5:0] bits must be set so that fACLK=10KHz.}
5 _{VDDR ≥ 3.13V}
NOTE
The LVR monitors the voltages V_DD, V_DDF and V_DDX. As soon as voltage
drops on these supplies which would prohibit the correct function of the
microcontroller, the LVR is triggering a reset.
