D950-Core
N:
Normalized
0: ALU result is not normalized (def.)
1: ALU result is normalized (bits 31 to 39 are equal & opposed to bit 30)
EXT:
Extension
0: The 8-bit extension is the sign of the 32-bit ALU result
1: The last ALU result overflows the 32-bit format
MOVF:Memorized overflow
0: Reset when tested by a conditional instruction (def.)
1: Set when the last ALU result overflows the 40-bit format
OVF: Overflow
0: An arithmetic overflows does not occur for the last 40-bit ALU result (def.)
1: An arithmetic overflow occurs for the last 40-bit ALU result
Z:
Zero
0: ALU result is different from zero (def.)
1: ALU result is zero
C:
Carry value generated out of bit 39 during the last ALU operation
S:
Sign
0: ALU result is positive (def.)
1: ALU result is negative
Note:‘-’ for bit 13 indicates RESERVED (read: 0, write: don't care)
