Switching RM48 Micro controller through software codes

Manjunathan,

Here is what is possible with just the RM48 itself:
1) you can switch off power internally to modules that you are not using, but this has only a small effect on power consumption.
see SPNU503b chapter 3 PMM power management module.
2) There are some low power modes that stop the clocks which reduces dynamic power consumption.
see SPNU503b chapter 2 section 2.4.3 and note that there is a static leakage portion of the device
power consumption that can be significant at high temperature.
