LM3S601 Microcontroller
8 General-Purpose Input/Outputs (GPIOs)
The GPIO module is composed of five physical GPIO blocks, each corresponding to an individual
GPIO port (Port A, Port B, Port C, Port D, and Port E, ). The GPIO module is FiRM-compliant and
supports 0-36 programmable input/output pins, depending on the peripherals being used.
The GPIO module has the following features:
■ Programmable control for GPIO interrupts
– Interrupt generation masking
– Edge-triggered on rising, falling, or both
– Level-sensitive on High or Low values
■ 5-V-tolerant input/outputs
■ Bit masking in both read and write operations through address lines
■ Programmable control for GPIO pad configuration
– Weak pull-up or pull-down resistors
– 2-mA, 4-mA, and 8-mA pad drive
– Slew rate control for the 8-mA drive
– Open drain enables
– Digital input enables
