6.1.12
Description: Reads the T bit, and conditionally branches. If T = 1, BT branches. If T = 0, BT
executes the next instruction. The branch destination is an address specified by PC +
displacement. However, in this case it is used for address calculation. The PC is the address 4
bytes after this instruction. The 8-bit displacement is sign-extended and doubled. Consequently,
the relative interval from the branch destination is –256 to +254 bytes. If the displacement is too
short to reach the branch destination, use BT with the BRA instruction or the like.
Note: When branching, requires three cycles; when not branching, one cycle.
Operation:

if ((d&0x80)==0) disp=(0x000000FF & (long)d);
else disp=(0xFFFFFF00 | (long)d);
if (T==1) PC=PC+(disp<<1);
else PC+=2;
