The wait mode puts the CPU in a loop in the boot ROM code and does not branch to the user application code. The device can enter the wait boot mode either through manually being set or because of some issue during boot up. Using the wait boot mode is recommended when using a debugger to avoid any JTAG issues. There is an infinite for loop when entered in wait boot so user can easily halt CPU and load code when connected using debugger.
