RS.L – IMM8 ⇒ NONE, only condition code ﬂags get updated

Subtracts the 8 bit constant IMM8 contained in the instruction code from the low byte of the source register

RS.L using binary subtraction and updates the condition code register accordingly.

Remark: There is no equivalent operation using triadic addressing. Comparing the values of two registers

can be performed by using the subtract instruction with R0 as destination register.

Set if bit 7 of the result is set; cleared otherwise.

Set if the 8 bit result is $00; cleared otherwise.

Set if a two´s complement overﬂow resulted from the 8 bit operation; cleared otherwise.

RS[7] & IMM8[7] & result[7] | RS[7] & IMM8[7] & result[7]

Set if there is a carry from the Bit 7 to Bit 8 of the result; cleared otherwise.
