11.6.5 Jump Effective Address
The jump effective address table indicates the number of clock periods needed
for the processor to calculate the specified effective address for the JMP or
JSR instructions. Fetch time is only included for the first level of indirection
All timing data assumes two-clock reads and writes.
I
on memory indirect addressing modes. The effective addresses are divided
is outside the parentheses. The number of read, prefetch, and write cycles
is given inside the parentheses as (r/p/w). The read, prefetch, and write cycles
are included in the total clock cycle number.
