Review Comment:
I'm open to another name. Any suggestions?
This was taken from Micron MT25QL512ABB datasheet:
> To reset the device, the RESET ENABLE command must be followed by the
RESET MEMORY
command. When the two commands are executed, **the device enters a power-on
reset con-
dition.** It is recommended to exit XIP mode before executing these two
commands.
All volatile lock bits, the volatile configuration register, the enhanced
volatile configura-
tion register, and the extended address register are reset to the power-on
reset default
condition according to nonvolatile configuration register settings.
