Operation in Power-Down State: The refresh controller operates in sleep mode. It does not
operate in hardware standby mode. In software standby mode RTCNT is initialized, but RFSHCR,
RTMCSR bits 5 to 3, and RTCOR retain their settings prior to the transition to software standby
mode.
Example 1: Connection to 2WE 1-Mbit DRAM (1-Mbyte Mode): Figure 7-7 shows typical
interconnections to a 2WE 1-Mbit DRAM, and the corresponding address map. Figure 7-8 shows
a setup procedure to be followed by a program for this example. After power-up the DRAM must
be refreshed to initialize its internal state. Initialization takes a certain length of time, which can be
measured by using an interrupt from another timer module, or by counting the number of times
RTMCSR bit 7 (CMF) is set. Note that no refresh cycle is executed for the first refresh request
after exit from the reset state or standby mode (the first time the CMF flag is set; see figure 7-3).
When using this example, check the DRAM device characteristics carefully and use a procedure
that fits them.
