Bit 7—Self-Refresh Mode (SRFMD): Specifies DRAM or pseudo-static RAM self-refresh
during software standby mode. When PSRAME = 1 and DRAME = 0, after the SRFMD bit is set
to 1, pseudo-static RAM can be self-refreshed when the H8/3002 enters software standby mode.
When PSRAME = 0 and DRAME = 1, after the SRFMD bit is set to 1, DRAM can be self-
refreshed when the H8/3002 enters software standby mode. In either case, the normal access state
resumes on exit from software standby mode.

Bit 6—PSRAM Enable (PSRAME) and Bit 5—DRAM Enable (DRAME): These bits enable
or disable connection of pseudo-static RAM and DRAM to area 3 of the external address space.
When DRAM or pseudo-static RAM is connected, the bus cycle and refresh cycle of area 3
consist of three states, regardless of the setting in the access state control register (ASTCR). If
AST3 = 0 in ASTCR, wait states cannot be inserted.
When the PSRAME or DRAME bit is set to 1, bits 0, 2, 3, and 4 in RFSHCR and registers
RTMCSR, RTCNT, and RTCOR are write-disabled, except that the CMF flag in RTMCSR can be
cleared by writing 0.
