AVR assembly - bit number to mask - Stack Overflow
AVR assembly - bit number to mask - Stack Overflow

In my ATtiny84a ,AVR, Assembly program I end up with a ,bit, number between 0 and 7, in a register, lets say r16. Now I need to create a ,mask, with that ,bit, number set. To make it more complicated, the timing of the operation must be the same, regardless of what ,bit, is set. For example if r16 = 5 the resulting ,mask, will be 0x20 (,bit, 5 set).

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 ...

For example, the first ,bit, (,bit, 0) of DDRB will determine if PB0 is an input or output, while the last ,bit, (,bit, 7) will determine if PB7 is an input or output. In PIC devices, a value of 1 is used for inputs and a value of 0 is used for outputs, but for ,AVR, devices the reverse is …

30/3/2019, · Using ,bit, to control pin in ,AVR, MCU. ... Another important term here is ,MASK BIT,, or simply ,MASK, is the ‘0b00001111’. ,Mask, define which ,bits, we want to modify. So far we’ve got.

Hence, the output that we get will contain all ,bits, as 0 except PC3 and PC0, where these two ,bits, will have the values read from the PINC command. ,Masking, techniques can not only be used while taking inputs, but also while reading ,bits, from certain registers and providing output as well.

Lets look at some examples. If you wanted to turn on the lowest ,bit, on PORTA, then you can simply write a 1 to PORTA because a 1, in 8 ,bit, binary, is really 00000001.. PORTA = 1; However, if you wanted to turn on the second lowest ,bit, on PORTA, then an easy way to do it is with a ,bit, …

Bit Masking, . ,Bits, in registers are given names. We will discuss TCCR1B later here, but for the time being assume that a register has a ,bit, named CS10. The usefulness comes out of the fact that you can set the CS10 ,bit, High just by executing:

From the truth table above, you can see that anything that is ANDed with a zero is zero. Lets say you wanted to clear the high ,bit, of a register, the following code will so just that: LDI A,0b1111_1111 ;A = 11111111 ANDI A,0b0111_1111 ;A = 01111111 "AND" operations can also be used with a ",bit,-,mask," to strip off ,bits, we are interested in.
