Refreshing and All-Module-Clocks-Stopped Mode: In this LSI, if the ACSE bit is set to 1 in
MSTPCRH, and then a SLEEP instruction is executed with the setting for all peripheral module
clocks to be stopped (MSTPCR = H'FFFF, EXMSTPCR = H'FFFF) or for operation of the 8-bit
timer module alone (MSTPCR = H'FFFE, EXMSTPCR = H'FFFF), and a transition is made to the
sleep state, the all-module-clocks-stopped mode is entered, in which the bus controller and I/O
port clocks are also stopped. As the bus controller clock is also stopped in this mode, CBR
refreshing is not executed. If DRAM is connected externally and DRAM data is to be retained in
sleep mode, the ACSE bit must be cleared to 0 in MSTPCRH.
6.6.13
When burst mode is selected on the DRAM interface, the DACK and EDACK output timing can
be selected with the DDS and EDDS bits in DRAMCR. When DRAM space is accessed in DMAC
or EXDMAC single address mode at the same time, these bits select whether or not burst access is
to be performed.
