NOTES:
a. This instruction interlocks the <ea> calculate and execute stages.
b. If the bit field spans a long-word boundary, add two clocks to the execute time. Two memory addresses are
accessed in this case.
c. If the bit field spans a long-word boundary, add seven clocks to both the <ea> calculate and execute times.
Two memory addresses are accessed in this case.
d. If the bit field spans a long-word boundary, add ten and nine clocks to both the <ea> calculate and execute
times, respectively. Two memory addresses are accessed in this case.
