2.12.1
binary number which is known to be less than 100, it can be quickly converted to BCD by
the following code:
Dividing the number by 10 leaves the tens digit in the low nibble of the Accumulator, and the
ones digit in the B register. The SWAP and ADD instructions move the tens digit to the high
nibble of the Accumulator, and the ones digit to the low nibble.

internal memory spaces, and the addressing modes that can be used with each one. The
MOV <dest>, <src> instruction allows data to be transferred between any two internal RAM
or SFR locations without going through the Accumulator. Remember, the Upper 128 bytes of
data RAM can be accessed only by indirect addressing, and SFR space only by direct
addressing.
