Forum Post: RE: set GPIO pin as Output on MSP430f5510 with internal pullup...
You can simply configure the pins as inputs with pull-up resistor. The voltage level is then set by the resistor. If the ESP reads the pins only after a reset, this might have been too late. If that is...

So what should I add to change the source of SMCLK? Actually am using the XT1 to configure ACLK and SMCLK. I am able to generate ACLK of 32kHz and SMCLK of 4.9MHz, i observed that since both use same...

The important things are GPIO 0,2, EN and 15 pins on recommended schematics ( bottom image left side ) Vcc to resistor and to the IC - we thought they are just current limiting and ignored them :(

XT1 and DCOCLKDIV are two different clocks. (It appears you are using XT1 as the reference clock for the FLL.) Anyway, to change the SMCLK source, change the SELS field in the UCSCTL4 register: UCSCTL4...

To quote the documentation: "On every reset/book/wakeup, GPIOxx MUST keep ...". The first reset happens before the MSP can initialize its pins, so you have no choice but to add resistors.

"top of the stack" means the upper end of the memory region that you have reserved for the stack. "Memory border" means the same. For example, if the SRAM ends at 0x23FF, and you initialize the stack...
