#158241 - Extracting high nibble Responding to: ???'s previous message |
It extracts the high-order nibble of the variable "mins".
If "mins" is stored in BCD format, i.e. one decimal digit stored in the high nibble and one decimal digit in the low nibble (such as 00 .. 59) you will get the tenths part of the minutes into A. If mins stores a binary value of 0 .. 255 minutes, then you will just divide that number with 16 and store the result in A. |
