With regards PFx on BF561
PF : What are the condition to be taken care of when using this port as a GPIO .
What happen when SPISEL7 is not used or SPI is used as a slave and TMR7 is ON , if PF7 still open to use as GPIO .
With best regards and wishes
In the BF561 there are no port mux registers so the muxing is decided by the setting of the Timer and SPI register settings. In order to use GPIO say PF7 either both SPI SPISEL7 and Timer7 should be disabled or if Timer7 is being used then in order to use PF7 as a GPIO timer output should be disabled by setting the 'OUT_DIS' in timer config register.
So SPISEL7 should be disabled in SPI_FLG register and timer should be disabled or running with output disabled to use PF7 as GPIO.
