Similar contention in a transition to self-refresh mode may prevent dependable strobe waveform output. This can also be avoided by clearing the BRLE bit to 0 in BRCR. • Immediately after self-refreshing is cleared, external bus release is possible during a given period until the start of a CPU cycle. Attention must be paid to the RAS state to ensure that the specification for the RAS precharge time immediately after self-refreshing is met. φ RFSH Refresh request BACK External bus released Refresh cycle CPU cycle Refresh cycle Figure 6.35 Bus-Released State and Refresh Cycles φ BREQ BACK Software standby mode Address bus Strobe Figure 6.36 Bus-Released State and Software Standby Mode |
