Serial interrupt programming in 8051 plays a significant role since it was used to perform interrupt operation through UART protocol. It plays a significant role in Embedded system Design where the controller has to perform a certain tasks based on the incoming character through the UART. Before go...
As before it includes a massive amount of information about the 8051-family of microcontrollers and techniques for programming them in the C language. There is a strong emphasis on interrupt-driven programming and operating systems as ... TW Schultz - 《Wood Island Prints》 被引量: 2发表: 200...

the programmer should explicitly clear the RXIS bit. Writing a 1 to this bit clears the RXRIS bit in the UARTRIS register and the RXMIS bit in the UARTMIS register.
Inside the while loop, we have done masking so that the next steps used in the programming can also be utilized. If masking not done the code execution will stop here only. ForPORTA ^= 1<<0, here theX-ORoperation is used. Its benefit is that it would performone time high and one ...
You can count overflows in another variable, and reset the timer with the time it took to save & restore your program state, increment the count and reset the timer. So I can keep resetting the timer interrupt within the interrupt routine itself while I can keep the records of overflow...
PCIE bit enables the pin change interrupt. Setting the pin enables this interrupt and in addition to this user need to configure the pins they wish to attach this interrupt. MCUCR – MCU Control Register ISC01 and ISC00 bits in MCUCR register is used to configure the point at which an ext...
locations The memory IC is organized internally as rows & columns. The 4164 has memory cells in a 128 by 256 matrix. There are two such matrix sections in a single 4164 i.e. 256 rows by 256 columns The 41256 has same organisation but is repeated four times. i.e. 512 rows by 512 ...
