I'd like to utilize GPIO ports J and M, more specifically bits PJ0:5 and PM4:6. I know those pins are multiplexed with another function, and I have found a mention about MUXCTL registers but I can't find, which values write to those registers to enable these pins. According to supplied libraries I think that writing and reading those registers is no problem (gpio_write_byte and gpio_read_byte) but really got stuck trying to solve this problem. Thanks for any help (a piece of code would be great:)
