Special Function Register (SRF) Of 8051 Microcontroller

Special function register

To monitors or control the various functions within a microcontroller like control different hardware peripherals like Timers, Serial Port, I/O Ports etc. Here we use some special registers in 8051 microcontroller called Special Function Register (SRF) (or Special Purpose Register, or simply Special Register). If we want to assess or change the operating mode of … Read more

Timer and counters in 8051 Microcontroller

There are many applications of microcontroller where we want to count external events such as generation of internal time delays between computer work and frequency of the pulse trains. This type of task is generally done by software techniques, but these software techniques will not give the exact result rather more important functions are not done. … Read more
