Section 4 Instruction Features
4.12.2
Table 4.24 shows the MSB detection instruction. The correspondence between the operands and
registers is the same as for ALU fixed decimal point operations. It is shown in table 4.25.

4.12.3
The DC bit is set as follows depending on the mode specified by the CS bits:
Carry/Borrow Mode: CS2–CS0 = 000: The DC bit is always 0.
Mode: CS2–CS0 = 001: Set to 1 for a negative operation result and 0 for a positive operation
result. In this mode, the DC bit has the same value as bit N.
Zero Mode: CS2–CS0 = 010: The DC bit is 1 when the operation result is zero; otherwise, the
DC bit is 0. In this mode, the DC bit has the same value as bit Z.
Overflow Mode: CS2–CS0 = 011: The DC bit is always 0. In this mode, the DC bit has the same
value as bit V.
Signed Greater Than Mode: CS2–CS0 = 100: Set to 1 for a positive operation result and 0 for a
negative operation result. In this mode, the DC bit has the same value as bit GT.
Signed Greater Than or Equal To Mode: CS2–CS0 = 101: Set to 1 for a positive or zero
operation result and 0 for a negative operation result.
