Refresh Cycle Priority Order: When there are simultaneous bus requests, the priority order is:
For details see section 6.3.7, Bus Arbiter Operation.
Wait State Insertion: When bit AST3 is set to 1 in ASTCR, the wait state controller (WSC) can
insert wait states into bus cycles and refresh cycles. For details see section 6.3.5, Wait Modes.
Self-Refresh Mode: Some pseudo-static RAM devices have a self-refresh function. After the
SRFMD bit is set to 1 in RFSHCR, when a transition to software standby mode occurs, the
H8/3003’s CS
self-refresh function can be used. On exit from software standby mode, the RFSH output goes
high.
Table 7-8 shows the pin states in software standby mode. Figure 7-16 shows the signal output
timing.
