There is a BUG in the compilation of a bit definition:
unsigned int bdata my_int; sbit bit15 = my_int ^ 15; sbit bit7 = my_int ^ 7; void main() { my_int = 0x8000; if(bit15) { // Here we shall not appear,as compiller // will be erroneous to check 7-bit of // a variable my_int instead of 15-bit // (as this variable place in memory in // little endian order) // ... } if(bit7) { // oops! we here! // ... } }
Do not stir bosh. Speak to the point. I have studied '51 architecture at once as soon as it has appeared. As it is the one-byte controller all other "wide" types of data are added by C-compiler. So C-compiler knows as data place in memory and it can take the necessary byte and to analyse necessary bit. I have declared the integer (16-bits) and I want at it 14-th bit. Instead of it I for some reason should read any ridiculous explanations and specify 6-bats. Unless it not absurdity?
