Data Sheet
Bytes are stored at even or odd byte addresses. Words are stored in ascending memory
locations with the low byte at an even byte address being followed by the high byte at
the next odd byte address. Double words (code only) are stored in ascending memory
locations as two subsequent words. Single bits are always stored in the specified bit
position at a word address. bit position 0 is the least significant bit of the byte at an even
byte address, and bit position 15 is the most significant bit of the byte at the next odd
byte address. bit addressing is supported for a part of the Special Function Registers, a
part of the internal RAM and for the General Purpose Registers.
Figure 9
Note: Byte units forming a single word or a double word must always be stored within
the same physical (internal, external, RAM) and organizational (page, segment)
memory area.
