Mode Select Bit — This bit controls the current operating mode during RESET high (inactive). The external
mode pin MODC determines the operating mode during RESET low (active). The state of the pin is registered
into the respective register bit after the RESET signal goes inactive (see
Write restrictions exist to disallow transitions between certain modes.
changes. Attempting non authorized transitions will not change the MODE bit, but it will block further writes to
the register bit except in special modes.
Write accesses to the MODE register are blocked when the device is secured.
