Example 2: Mode transition to the PCM
Condition: SDRAM= Self-refresh mode
;((( Entry Self Refresh mode )))
ABP:
;((( Entry PMC mode )))
;--- PLL off setting -----
; After Wake-up
Note: SDRAMC is initialized by hot reset upon a wake-up.
The SDCKE pin output is initialized to 1 by initializing the SDRAMC. Therefore, SDRAM exits from self-refresh
mode. Auto-refresh function of the SDRAMC register is disabled at same time. Therefore, SDRAM data might
be lost.
However, though the SDRAMC is initialized by hot reset, port configurations are not initialized by Hot reset.
Thus, SDRAM can retain its contents.
To keep SDRAM data, program the PJ7 pin as the SDCKE pin and drive it low before entering the PMC mode.
The output level of the PJ7 pin while in PMC mode is determined by the PJ and PJDR register settings. Please
program the PJ7 pinto be driven low while in PMC mode in the same manner as shown above.
