Other Parts Discussed in Thread: TEST
A question related to an unintended reset. Unintentional reset has also occurred in LPM2.
At that time, when SYSRSTIV was read, it was SYSRSTIV = 0x000E.
This flag indicates that the voltage has dropped, but no matter how many times the voltage is checked, no voltage drop has occurred.
The cause will be investigated in the future, but first, we want to prevent the reset of the voltage drop factor from occurring. There is a bit called PMMLPRST in bit7 of the PMMCTL0 register. Previously (slau367b) it seemed that this could be set to 1 to avoid a reset, but in the current user guide (slau367o) bit7 is Reserved and the description is Reserved. Must be written with 0 . The customer really want to avoid being reset, but can't use it? Is there a workaround if the customer can take the risk?
