I am studing WSN and in MSP430 CPU from Texas Instruments, i faced PMMCOREV. I tryed to find out what this is but i could not found something. Can anyone tell me what does it stand for?

Solution

  • Section 2.2.1 of the User's Guide says:

    Higher MCLK speeds require higher levels of VCORE. Higher levels of VCORE consume more power, and so the core voltage has been made programmable in up to four steps to allow it to provide only as much power as is required for a given MCLK setting. The level is controlled by the PMMCOREV bits.
