Switching boot mode without cycling power

Hello Community,

 

If I wish to change the boot mode / boot configuration  of the 8M Mini, is it necessary to power the processor down completely before doing so? Or is it acceptable to simply assert signal POR_B, change the BOOT_MODE and BOOT_CFG pins, and then de-assert signal POR_B?

Also, is it necessary for BOOT_MODE, TEST_MODE, and other boot configuration inputs to be pulled high or low through a resistor? Or can the inputs be tied directly to NVCC_JTAG or GND?

 

Thanks
