Idle Time Between Different Bus Access Transitions (BTMODE = 0)

OMAP3.2 Subsystem

After a read completion, if no other access (RD, WR) is pending, the data

bus is driven with the previous read value. The bus turn-around time (OE

going high to direction going out) is a minimum of 1 TC_CK cycle and can

be extended through BTWST.

Table 1 shows the bus turn around cycles inserted for various transitions

with EMIFS when BTMODE=0.
