I'm designing my application based on MSP430F6735 and I need to use Real Time Clock Module (RTC) with backup battery, this make me must put a crystal 32.768KHz and when i search when i put the high frequancy crystal i didn't found a place to it.
it supposed that this controller can work up to 25 MHz and when i read the device user guide (MSP430x6xx) i found that i can connect low power frequency X1 and high frequency X2 but in pin description i found only Xin and Xout.
could any one tell me how can i connect the low frequency crystal for RTC and the high frequency for my application in this controller?
