Section 9 Bus Controller (BSC)
9.9.6
An extension cycle (Tmaw) can be inserted between Tma1 and Tma2 cycles to extend the AH
signal output period by setting the ADDEX bit in MPXCR. By inserting the Tmaw cycle, the
address setup for AH and the AH minimum pulse width can be assured.
Figure 9.33 shows the access timing when the address cycle is three cycles.
