MSP432P401R: Timer32 counting rate

Part Number: MSP432P401R

Hello,

I was hoping someone could point me in the direction of where it describes the counting rate of the Timer32 module. We are trying to use it as a timestamp for UART messages but cannot figure out at what rate the Timer32 counts down.

Our initial assumption was that the timer decrements at the same rate of the source clock; since we are using a 48 MHz MCLK, that would mean 48 million ticks per second with a prescalar of 1. However, we experimentally measured it to be closer to 5 million ticks per second, which is rather confusing.

Is there somewhere in the MSP432 documentation to that explains exactly at what rate the Timer32 module ticks?

Thank you!
