-After a system or power Reset, ​W7500 is in Run mode. There are two low power modes to save power when CPU does not need to keep running. ​For example ​when CPU waiting for an external ​event, user can enter the low power modeAnd W7500 don’t have power-off mode.+W7500 is in RUN mode after a system or power reset. There are two low power modes to save power when the CPU does not need to be kept running. ​These modes are useful for instances like when the CPU is waiting for an external ​interruptPlease note that there is no power-off mode for W7500.
