WebMay 6, 2024 · My application requires that I store the value in a 16 bit counter but due to pcb issues it requires that the lower 8 bits of the counter be reversed (01001110 to 01110010). The code is being written in C (GCC) and the counter register is "int" type (16 bits). My application is using an Atmel ATtiny 8 bit MCU.

In C, true is represented by 1, and false by 0. However, in a comparison, any non-false value is treated is true. The ! operator does boolean inversion, so !0 is 1 and !1 is 0. The ~ operator, however, does bitwise inversion, where every bit in the value is replaced with its inverse. So ~0 is 0xffffffff (-1). ~1 is 0xfffffffe (-2). orchids blooms falling offWebProgram Explanation. 1. Take the input from the user and store it in “n” variable. 2. For a given integer n, the basic idea is to loop through each bit of ‘n’ from right end (right-shift) and keep shifting ‘rev_bits’ from left end (left-shift). rev_bits = rev_bits << 1; n = n >> 1; 3.
