The special function register (SFR) mounted depend on the product. See 3.2.3 Special function registers
(SFRs).
During reset signal generation or oscillation stabilization time wait, only the PC contents among the hardware
statuses become undefined. All other hardware statuses remain unchanged after reset.
These values vary depending on the reset source.
