According to Motorola's Programer's Reference Manual (1984)
"… if a data register is the destination, then the bit number is modulo 32,
allowing bit manipulation on all bits in a register. If a memory location is
the destination, a byte is read from that location,and the bit operation
performed using the bit number modulo 8 with zero referring to the
least-significant bit."
