APB/AHB freq TM4C123gh6pm

VT
Genius 3300 points

1. Datsheet says APB is legacy bus, so i guess now all the peripherals are on AHB bus, right?

2. What is the freq of AHB freq. Is it always equal to system clock freq?

3. Is there any clock configuration utility for this MCU?

    Hello Vindhyachal

    The frequency on all peripherals is the system clock for the interface. It is the path that an access takes which decides the max rate of access. There is no clock configuration on the MCU except for the GPIOHBCTL register in Sysctl space to select between APB and AHB access
