2.3
The eight data registers support data operands of 1, 8, 16, or 32 bits. The seven address
registers and the active stack pointer support address operands of 32 bits.
2.3.1 Data Registers
Each data register is 32 bits wide. Byte operands occupy the low-order 8 bits, word
operands the low-order 16 bits, and long-word operands, the entire 32 bits. The least
significant bit is addressed as bit zero; the most significant bit is addressed as bit 31.

1 for byte, 2 for word, and 4 for long word. If An is the stack pointer and
the operand size is byte, N = 2 to keep the stack pointer on a word boundary.
