n Bit location to be tested
Function
•
Checks the contents of the nth bit of the I/O (word or double word) specified by d, and if the result is "1," '1' is set to C
(R7F0). If the result is "0," C (R7F0) is reset to "0."
•
The contents of d remains unaltered.

If d is a word: Designates the bit location depending on the contents (0 to 15) of the lower 4 bits (b3 to b0) of n (WX,
WY, WR, WM, TC). (Upper bits are ignored and considered as "0.")
The n (constant) can be set to 0 to 15 (decimal).
If d is a double word: Designates the bit location depending on the contents (0 to 31) of the lower 5 bits (b4 to b0) of n (WX,
WY, WR, WM, TC). (Upper bits are ignored and considered as "0.")
The n (constant) can be set to 0 to 31 (decimal).
