N
Set/Clear N Bit
N
The N command sets the N bit of the condition code register (CCR) to
the specified value.
NOTE:
The CCR bit designators are at the lower right of the CPU window. The
CCR pattern is V11HINZC (V is two’s complement overflow for
M68HC08 MCU only and is 1 for M68HC05 MCU, H is half-carry, I is IRQ
interrupt mask, N is negative, Z is zero, and C is carry). A letter in these
designators means that the corresponding bit of the CCR is set; a period
means that the corresponding bit is clear.
Syntax:
N 0|1
Where:
0
Clears the N bit
1
Sets the N bit
Example:
>N 1
Set the N bit of the CCR.
