Chapter 10 XGATE (S12XGATEV3)
10.8.2.2
All logic and arithmetic instructions support the 8 bit immediate addressing mode (IMM8: RD = RD ∗
#IMM8) and the triadic addressing mode (TRI: RD = RS1 ∗ RS2).
All arithmetic is considered as signed, sign, overflow, zero and carry flag will be updated. The carry will
not be affected for logical operations.
10.8.2.3
This group comprises transfers from and to some special registers
Branch Instructions
The branch offset is +255 words or -256 words counted from the beginning of the next instruction. Since
instructions have a fixed 16 bit width, the branch offsets are word aligned by shifting the offset value by 2.
An unconditional branch allows a +511 words or -512 words branch distance.
10.8.2.4
Shift operations allow the use of a 4 bit wide immediate value to identify a shift width within a 16 bit word.
For shift operations a value of 0 does not shift at all, while a value of 15 shifts the register RD by 15 bits.
In a second form the shift value is contained in the bits 3:0 of the register RS.
