The maximum clock frequency of the TM4C123GH6PMI is 80 MHz.
The pin muxing on the TM4C123GH6PMI 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.
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.
The ADC on the TM4C123GH6PMI can be used by configuring the ADC control registers (ADCCTLn) and the ADC sequence registers (ADCSEQn). Refer to the datasheet for specific register addresses and bit fields.
The NMI (Non-Maskable Interrupt) pin is used to trigger an interrupt that cannot be masked by the CPU, and the RESET pin is used to reset the microcontroller.
