Texas Instruments TM4C1294NCPDT User Manual

Register 89: General-Purpose Input/Output Run Mode Clock Gating Control
(RCGCGPIO), offset 0x608
The RCGCGPIO register provides software the capability to enable and disable GPIO modules in
Run mode. When enabled, a module is provided a clock and accesses to module registers are
allowed. When disabled, the clock is disabled to save power and accesses to module registers
generate a bus fault.
Important: This register should be used to control the clocking for the GPIO modules.
