(Note)
NOTE: HOLD is sampled on the rising edge of CLKIN. The processor asserts HOLDA to grant the bus on the
same edge in which it recognizes HOLD if the last state was T_i or the last T_r of a bus transaction. Similarly,
the processor deasserts HOLDA on the same edge in which it recognizes the deassertion of HOLD.
