so I am testing out the PulseSensor code from here: https://github.com/WorldFamousElectronics/PulseSensorAmped_2_Sensors/tree/master/PulseSensorAmped_2_Sensors_1.5.0
In the interrupt.ino file, there is a function interruptSetup() which initializes the timer settings. However, I want to undo these settings first, as I have found out that this function is affecting my other readings. What is the default settings for the timer?
