13/6/2014, · ,Bit, toggle is also useful. So for this we make use of the property of ex-or as follows. x ex-or 1 = complement of x or x-bar. Thus if you ex-or the ,bit, with 1 the ,bit, will be toggled. Example. R &= 0x2081 // This is the ,masking, operation in embedded c. R |= 0x2081 // This will set the ,bits, 0,7,13. R ^= 0x2081 // This will toggle ,bits, 0,7,13

ISC11, ISC10, ISC01, ISC00: Interrupt Sense Control ,Bit, 1 and ,Bit, 0 for interrupt 1 and interrupt 0. The External Interrupt 1 is activated by the external pin INT1, if the SREG I-,bit, and the corresponding interrupt ,mask, in the GICR are set. The level and edges on the external INT1 pin that activate the interrupt are defined in table below.

The PCIEx ,bits, in the PCICR registers enable External Interrupts and tells the MCU to check PCMSKx on a pin change state. When a pin changes states (HIGH to LOW, or LOW to HIGH) and the corresponding PCINTx ,bit, in the PCMSKx register is HIGH the corresponding PCIFx ,bit, in the PCIFR register is set to HIGH and the MCU jumps to the corresponding Interrupt vector.

Timers - Your AVR starting point!
Timers - Your AVR starting point!

An ,AVR, at 8 MHz and a timer prescaler can count (when using a 16-,bit, timer) (0xFFFF + 1) * 1024 clock cycles = 67108864 clock cycles which is 8.388608 seconds. As the prescaler increments the timer every 1024 clock cycles, the resolution is 1024 clock cycles as well: 1024 clock cycles = 0.000128 seconds compared to 0.125µs resolution and a range of 0.008192 seconds without prescaler.

microcontroller - Why does AVR code use bit shifting ...

For some ,AVR bit, manipulation assembler instructions (e.g. SBI, CBI, BST, BLD) you have to use ,bit, indices as immediate operator in their instruction op code. Only if you identify ,bits, of SFRs by indices (not by ,bit mask,) you can use such identifiers directly as the assembler instructions immediate operand.

Bit manipulation - Wikipedia
Bit manipulation - Wikipedia

Source code that does ,bit, manipulation makes use of the bitwise operations: AND, OR, XOR, NOT, and possibly other operations analogous to the boolean operators; there are also ,bit, shifts and operations to count ones and zeros, find high and low one or zero, set, reset and test ,bits,, extract and insert fields, ,mask, and zero fields, gather and scatter ,bits, to and from specified ,bit, positions or ...
