8051 reset circuit. 
The 8051 has an active high reset input must 0 high for two machine cycle when power is first applied and then goes to low. The simple RC circuit used to supply system voltage(VCC) to the reset pin until the capacitor charge. At a threshold of about 2.5v, the reset input reaches a low level and the system begins to run. The reset button enables the user to reset the system with out having to turn power off and on.

Clock circuit of 8051 The 8051 has on chip oscillator pin XTAL1 and XTAL2 are provided for connecting a resonant network to from an oscillator crystal frequency ranges from 1 MHZ to 24 MHZ. Ceramic resonators may be used as a low-cost alternative to crystal resonators but due to decrease in frequency stability and accuracy, ceramic resonators are not preferred for high-speed serial data communication with other system. The oscillator formed by the crystal, capacitors, and on chip inverter generates pulse train at the frequency of the crystal as shown in fig. The clock frequency & establishes the smallest interval of time within the microcontroller, called the pulse, p, time. The smallest interval of time to accomplish any simple instruction, or part of a complex instruction, however, is the machine cycle. The machine cycle is made up of six states. A state is the basic time interval for discrete operations of the microcontroller such as fetching on encode byte decodin

Program Status Register PSW of 8051 The 8051 has a 8-bit PSW register which is alsoknown as Flag register.In the 8-bit register only 6-bits are used by 8051.The two unused bits are user definable bits.In the 6-bits four of them are conditional flags .They are Carry –CY,Auxiliary Carry-AC, Parity-P,and Overflow-OV .These flag bits indicate some conditions that resulted after an instruction was executed. The bits PSW3 and  PSW4  are  denoted as RS0 and RS1 and these bits are used th select the bank registers of the RAM location. The meaning of various bits of PSW register is shown below. CY                              PSW.7                       Carry Flag AC                              PSW.6                       Auxiliary Carry Flag FO                              PSW.5                        Flag 0 available for general purpose . RS1                            PSW.4                        Register Bank select bit 1 RS0                            PSW.3
