32.14.1.5 Explanation of the SHL and SHLP Instructions
When the SHL or SHLP instruction is executed, the S1 bits are
shifted to the right of the S2 number of bits. Every time 1 bit is
shifted, the leftmost bit (the most significant bit) is lost. 0 is
stored in the bottom-most empty bit. The result is stored in
D1.
The SHL and SHLP instructions always pass power. When using SHL
and SHLP instructions, an error will occur if the variables
specified in operands S1 and D1 are not the same type. Designate
the same variable type in operands S1 and D1.
Refer to the following for specifying a constant.
Specify the address to shift.
Specifies the number of bits to shift.
Specifies the address to store the shift
result.
For example, when 1 bit is shifted left
When operand D1 is an integer variable
When operand D1 is an integer variable and
you want to input hexadecimal values in operands S1 and S2
When 0x (zero and lower case "x") is input, the following values
become hexadecimal values.
Use the same format when shifting data in a specified array
(integer variable array) and when specifying an array element.
An error will occur if the formats are different.
If the S1 and D1 arrays are the same size, S1 is treated like a
single giant integer. Bits are shifted one element to the next
element.
The topmost bits of each element are not lost. However, the
topmost bit in the last element is lost. Specify S2 as 0 or higher,
up to (32 x Array Size -1).
If both S1 and D1 are not arrays, 32 bits are shifted. For S2,
specify a value between 0 and 31.
