Texas Instruments TM4C1294NCPDT User Manual

Register 26: GPIO 12-mA Drive Select (GPIODR12R), offset 0x53C
The GPIODR12R register is the 12-mA drive control register. Each GPIO signal in the port can be
individually configured without affecting the other pads.
Note: This register has no effect on port pins PL6 and PL7 or PM[7:4].

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

Output Pad 12-mA Drive Enable
DescriptionValue
The drive for the corresponding GPIO pin is controlled by the
GPIODR2R, GPIODR4R, and/or the GPIODR8R register.
0
The corresponding GPIO pin has 12-mA drive. This encoding
is only valid if the GPIOPP EDE bit is set and the appropriate
GPIOPC EDM bit field is programmed to 0x3.

Note: Please refer to Table 10-3 on page 753 for information on how
to configure the drive strength.
Changes in the GPIODR2R, the GPIODR4R register and/or the
GPIODR8R registers to configure 12 mA are effective on the next clock
cycle.
