6.9.6 Address
Cycle
Control
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 6.30 shows the access timing when the address cycle is three cycles.
