Hi,
I observed that GPIO Port F start and end addresses on the Tiva C Series Launchpad are 0x4002.5000 0x4002.5FFF ( http://www.ti.com/lit/ds/symlink/tm4c123gh6pm.pdf page 91 ).
That would imply there 8 registers ( 0x000 to 0xFFF = 256 bits , 32 bits per register => 8 registers ) on GPIO Port F.
However, when i take a look at the schematic ( page 20 www.ti.com/lit/ug/spmu296/spmu296.pdf ) I just see PF0 to PF4 ( so that's 5 Registers ). What is the rest of the memory ( the ones which would have been used for PF5 to PF7 ) used for ?
-- Update --
Got it, A similar part ( http://www.ti.com/lit/ds/symlink/tm4c123gh6pge.pdf ) in 144LQFP has all 8 pins.
Thanks !
