What are the commonly used reset circuits for MCS-51 microcontrollers? What is the initial state of the machine after reset?

Answer: There are two types of reset circuits: power-on automatic reset circuit and manual reset circuit. After reset, the program counter PC changes to 0000H, and the microcontroller starts executing from the program memory address 0000H unit. Except P0~P3 is FFH; SP is 07H; SBUF is uncertain. Most special function registers are cleared.
