Explanation of function and operation

1. 16-bit operation (SFR and SFRP)

16 bits stored in a word device

Specify a value ranging from "0" to "15" as "n".

If "16" or larger value is specified as "n", 16 bits are shifted rightward by the remainder of "n/16".

For example, when "n" is set to "18", 16 bits are shifted rightward by 2 bits (18/16 = 1 ... 2).

The ON (1)/OFF (0) status of the "n"th bit (bit "n-1") in the word device

"0" is set to "n" bits from the most significant bit.

In the case of "n = 6"
