Out of the factory, the eZ80 is totally ignorant: it comes with 256 KB of empty flash memory. This reads as $FF, which corresponds to the “RST 38h“ instruction, a one-byte call to address $0038 (mixed $-vs-h notations are used for hex numbers: “$” in Forth, “h” for Z80).
Left alone, the eZ80 will continuously execute this instruction, cycling through its address space since the stack pointer will be constantly decremented.
