DC characteristics
The figures in Table 1: reflect the specifications of the voltage and current regulators
within the UEM.
1 Controlled by MCU writing to UEM references register.
2 The second current value indicates the maximum possible output current of the regulator when
in low quiescent mode.
3 The output voltages are split into two different current categories. The upper part is the lower
range of output current, and the lower part is the higher range of output current.
4 UEMSLX is slave to SleepX from the UPP. Sets the UEM into sleep mode.
5 Condition in sleep-mode depends on MCU writings to UEM regulator registers solely.
6 Condition in sleep-mode depends on DSP writings to UEM register.
