#136639 - Evaluate it yourself! Responding to: ???'s previous message |
You get the result of ReadRegister(MSG_D) & 0x08, which assuming unsigned chars will be either 0x00 or 0x08, which logically is FALSE or TRUE the we have the logical NOT operator ! that reverses the result. The while operator executes the following block when TRUE. In your instance there is no code block, so the while will fall through when the result is FALSE. Put it all together you get while bit3 of register MSD_D is 0, loop, otherwise drop through |
