If voltage is recovered after the power supply has decreased from 1.2 V to 0.8 V due to power glitch, is there any possibility that the CPU malfunctions?
• Answer :If the power supply is turned on after it has decreased to a halfway voltage (1.0 V or lower), the register that was not initialized despite power-on reset by the CG1 and CG0 bits of the LPMCR register may be started.For this reason, normal operation may be unable to be confirmed if the register starts operating at the slower clock cycle that the software does not intend.In this case, initialize the register with the initial routine or use HSTX instead of external reset.
