Data Formats

The H8SX 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.
