Bit Manipulation Instruction Execution Times

This table indicates the number of clock periods required for the bit
manipulation instructions. The number of read and write cycles is shown in 
parenthesis as (r/w). The number of clock periods and the number of read and 
write cycles must be added respectively to those of the effective address
calculation where indicated.
