Power-Up: After power-up, the 71M6513/6513H is in reset as long as V1 < VBIAS. As soon as V1 exceeds VBIAS, the reset
timer is started which takes the MPU out of reset after 4100 oscillator cycles (see Figure 20). The MPU then initiates its pre-
boot phase lasting 32 cycles. The supply current will be low but not zero during power-up. It will increase, once V1 exceeds
VBIAS and will increase to the nominal value once the preboot phase starts. The supply current may then be reduced under
firmware control, following the steps specified in Battery Operation and Power Save Modes.

Battery Operation
When V1 is lower than VBIAS, the external battery will power the following parts of the 71M6513/6513H:
RTC
Crystal oscillator circuitry
MPU XRAM
WD_OVF bit
Power Save Modes
In normal mode of operation, running on 3.3V supply, various resources of the 71M6513/6513H may be shut down by the
MPU firmware in order to reduce power consumption while other essential resources such as UARTs may remain active.
Table 59 outlines these resources and their typical current consumption (based on initial condition MPU_DIV = 0).

*) This bit is to be used with caution! Inadvertently setting this bit will inhibit access to the part with the ICE interface and thus
preclude flash erase and programming operations.
