#right mouse button(s)
Thanks for the prompt response, Shraddhan. Bits 10 & 14 correspond to the right
mouse buttons, and will be cleared if the respective button is
depressed(closing the circuit). The cmp.w is unnecessary, and could be replaced
with a BTST.W instruction. However, I was uncertain as to whether the BTST.W
could be used on $Dff016 (a read-only location).
