Before the instruction
is executed
After the instruction
is executed
Additional remarks
1. If S +n-1, S +n-1, or D+n-1 exceeds the device range, the instruction is not executed, SM0 is ON, and the error
1 2
code in SR0 is 16#2003.
2. If n is not between 1–256, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#200B.
3. Explanation of matrix instructions:

A matrix is composed of more than one 16-bit register. The number of registers in a matrix is the length of the
array n. There are 16×n bits in a matrix, and the matrix operation is performed on one bit at a time.

The matrix instruction takes the 16×n bits in a matrix as a string of bits, rather than as values. The matrix
operation is performed on each bit.

Matrix instructions mainly process the one-to-many or many-to-many status, such as moving, copying,
comparing, and searching by bit.

You must specify a 16-bit register for the matrix instruction. The 16-bit register specifies a certain bit among
the 16n bits in the matrix for the operation, and the 16-bit register is called the pointer. The value in the
register is between 0–16n-1, and corresponds to the bit between b0–b16n-1.

Shifting or rotating of the specified data can be involved in the matrix operation. Note that the bit number
decreases from the left to the right, as illustrated below.
