The special function registers (SFRs) mounted depend on the product. Refer to 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.
