Data Formats  
The H8/300 CPU can process 1-bit data, 4-bit (BCD) data, 8-bit (byte) data, and 16-bit (word)  
data.  
Bit manipulation instructions operate on 1-bit data specified as bit n (n = 0, 1, 2, ..., 7) in a byte  
operand.  
All arithmetic and logic instructions except ADDS and SUBS can operate on byte data.  
The DAA and DAS instruction perform decimal arithmetic adjustments on byte data in packed  
BCD form. Each nibble of the byte is treated as a decimal digit.  
The MOV.W, ADD.W, SUB.W, CMP.W, ADDS, SUBS, MULXU (8 bits × 8 bits), and  
DIVXU (16 bits ÷ 8 bits) instructions operate on word data.
