The CPU internal state and the registers of on-chip peripheral modules are initialized, with the
I bit of the condition code register (CCR) set to 1.
The PC is loaded from the reset exception handling vector address (H'0000 to H'0001), after
which the program starts executing from the address indicated in PC.
