Count/Register field—Specifies shift count or register that contains the shift count:
For ASR, the operand is shifted right; the number of positions shifted is the shift count.
Bits shifted out of the low-order bit go to both the carry and the extend bits; the sign bit
(MSB) is shifted into the high-order bit.
X — Set according to the last bit shifted out of the operand; unaffected for a shift
N — Set if the most significant bit of the result is set; cleared otherwise.
Z — Set if the result is zero; cleared otherwise.
V — Set if the most significant bit is changed at any time during the shift operation;
C — Set according to the last bit shifted out of the operand; cleared for a shift count
If i/r = 1, this field specifies the data register that contains the shift count (modulo 64).
If i/r = 0, this field contains the shift count. The values 1 – 7 represent counts of 1 –
