TM4C123GH6PMIR datasheet by Texas Instruments

TM4C123GH6PMIR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency of the TM4C123GH6PMIR?
  The maximum clock frequency of the TM4C123GH6PMIR is 80 MHz.
• How do I configure the pin muxing on the TM4C123GH6PMIR?
  The pin muxing on the TM4C123GH6PMIR can be configured using the Pin Muxing Register (PMCn) and the Pin Configuration Register (PCn). Refer to the datasheet for specific register addresses and bit fields.
• What is the purpose of the VDDA and VDD pins on the TM4C123GH6PMIR?
  The VDDA pin is the analog power supply pin, and the VDD pin is the digital power supply pin. Both pins should be connected to a power source, and decoupling capacitors should be used to filter out noise.
• How do I use the internal oscillator on the TM4C123GH6PMIR?
  The internal oscillator on the TM4C123GH6PMIR can be enabled by setting the OSCSRC bit in the System Control Register (SYSCTL_RCC). The oscillator frequency can be adjusted using the RCFREQ bits in the same register.
• What is the maximum current rating of the GPIO pins on the TM4C123GH6PMIR?
  The maximum current rating of the GPIO pins on the TM4C123GH6PMIR is 4 mA per pin. However, the total current drawn from the VDD pin should not exceed 100 mA.
