What is the purpose of GPIO in a MCU?
A General Purpose Input/output (GPIO) is an interface available on most modern microcontrollers (MCU) to provide an ease of access to the devices internal properties. Generally there are multiple GPIO pins on a single MCU for the use of multiple interaction so simultaneous application.
How many ports are there in a GPIO module?
On the LM3S8962 the GPIO modules consist of seven separate blocks, each of these blocks will corresponding to individual ports on the GPIO interface, the ports in order are: (Port A, Port B, Port C, Port D, Port E, Port F, Port G).
What can a GPIO do for a CPU?
In many applications, the GPIOs can be configured as interrupt lines for a CPU to signal immediate processing of input lines. In many newer designs, they also have the ability to control and use Direct Memory Access (DMA) to transfer blocks of data in a more efficient manner.

What is the general purpose of GPIO pins?
The use of General Purpose Input/Outputs is a realization of open ended transmission between devices on an embedded level. These pins available on a processor can be programmed to be used to either accept input or provide output to external devices depending on user desires and applications requirements.
How are GPIO pins used in test systems?
The GPIO pins can be an effective way to monitor and display information about the system in a real time basis. GPIO pins can be used at any time in test execution to display any pertinent information about the program. GPIO ports, a program or sequence of operations can be easily followed on the hardware level.
How to control power up and power down sequence?
We offer the easiest method to control the power up and power down sequence of multiple power supplies. Discrete solutions with a combination of resistors and capacitors can provide power-up sequencing, but by themselves cannot provide a reverse sequence during power down. The LM3880 and LM3881 simple power supply sequencers offer:
What does the ucd90x power supply sequencer do?
The UCD90x family of digital power supply sequencers, also known as system health monitors, provides a comprehensive digital solution for complex power systems: Configurable power-up and power-down sequence control for up to 24 power rails based on timing and/or dependencies (rail and/or pin)
