Section 23 Power-Down Modes
23.4
Output of the SDRAMφ clock can be controlled by the SDPSTP bit in SCKCR. When the
SDPSTP bit is set to 1, the SDRAMφ clock stops at the end of the bus cycle and the pin can be
used as a general port. SDRAMφ clock output is enabled when the SDPSTP bit is cleared to 0
regardless of the DDR value. Table 23.5 shows the state of the SDRAMφ pin in each processing
state.
Note: The SDRAM interface is not supported by the H8S/2426 group and H8S/2424 group.
Table 23.5 SDRAMφ Pin State in Each Processing State
Note: SDRAM is not available in the H8S/2426 and H8S/2424 Groups.
