Reset values in the preceding table are the default values of the bits when peripherals are not configured using the software. If the peripheral is enabled using the software then the default reset value for that bit is 0x0.
Important: Do not change these register fields dynamically for
005 and 010 devices, see System Registers Behavior for M2S005/010 Devices.
