I am using IMX93 EVK where I required to reduce cpu frequency of A core which is currently 1600MHz.
I want to reduce it up to 200MHz,
Earlier for IMX8ULP EVK I followed below method and I was able to control frequency on A core with accessing appropriate resisters
# Switch a35 to FRO 192 MHz /unit_tests/memtool -32 0x292c0014=0x08000000 # Set PLLEN to 0 /unit_tests/memtool -32 0x292c0500=0x03000000 # Read and set the division and multiplication factors /unit_tests/memtool -32 0x292c0014 1 /unit_tests/memtool -32 0x292c0510 1 # Set PLLEN to 1" /unit_tests/memtool -32 0x292c0500=0x03000001 # Switch a35 to PLL2" /unit_tests/memtool -32 0x292c0014=0x18000000 mhz
I checked reference manual of IMX93, but I am not able to get resistor by which I can control clock,
Can anyone guide me on this?

Hi,
Thank you for your interest in NXP Semiconductor products,
CPU Frequency is changed between Low Power Modes (ND, OD, etc.). Please refer to this post.
