The following sequence is carried out when reset exception handling begins.
1. The internal state of the CPU and the registers of the on-chip supporting modules are
2. The CPU loads the program counter with the first word in the vector table (stored at addresses
The RES pin should be held low when power is switched off, as well as when power is switched
on.
