How to understand this sentence"All multiplexed signals may enter a high-impedance state when the configured fuction is input-only or the configured function supports high-Z operation"in the note of OMAP-L138 datasheet?

For example,I need several DSP pins that have the high-impedance state before bootload code from a external Flash.This pins connect to the Flash high address lines.Afterwards,these pins will be as GPIOs to control the Flash high address lines.I know these pins like GP0[1],GP0[2],GP[3] meet my needs.

I wonder whether pins like GP0[15],GP0[11],GP0[10] meet my needs? As we all know,PINMUX registers have default value after reset or OMAP-L138 startup.As the same time,Pins like GP0[15],GP0[11],GP0[10] select the function PRU,but their type is INPUT.As this sentence in the Brief Description of the Problem above,can I understand these pins also have the high-impedance state?

thank  you!
