• Manufacturer: Hitachi Semiconductor

3.4 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
• 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
• The MOV.W, ADD.W, SUB.W, CMP.W, ADDS, SUBS, MULXU (8 bits 8 bits), and DIVXU
operand.
BCD form. Each nibble of the byte is treated as a decimal digit.
(16 bits ÷ 8 bits) instructions operate on word data.
