Chapter 10 XGATE (S12XGATEV3)

n = RS or IMM4

Shifts the bits in register RD n positions to the right. The higher n bits of the register RD become ﬁlled

with zeros. The carry ﬂag will be updated to the bit contained in RD[n-1] before the shift for n > 0.

n can range from 0 to 16.

In immediate address mode, n is determined by the operand IMM4. n is considered to be 16 in IMM4 is

In dyadic address mode, n is determined by the content of RS. n is considered to be 16 if the content of RS

is greater than 15.

Code and CPU Cycles

LSR RD, #IMM4

Set if bit 15 of the result is set; cleared otherwise.

Set if the result is $0000; cleared otherwise.

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

Set if n > 0 and RD[n-1] = 1; if n = 0 unaffected.
