Section 2 CPU
2.5
The H8/300H CPU can process 1-bit, 4-bit (BCD), 8-bit (byte), 16-bit (word), and 32-bit
(longword) data. Bit-manipulation instructions operate on 1-bit data by accessing bit n (n = 0, 1,
2, …, 7) of byte operand data. The DAA and DAS decimal-adjust instructions treat byte data as
two digits of 4-bit BCD data.
