This field is transmitted to the SDRAM during initialization to select the SDRAM strength of data output. This parameter must be
set according to the SDRAM device specification.
After initialization, as soon as this field is modified and self refresh mode is activated, the Extended Mode Register of the
SDRAM device is accessed automatically and its DS parameter value is updated before entry in self refresh mode.
This field is transmitted to the SDRAM during initialization to set the refresh interval during self refresh mode depending on the
temperature of the low power SDRAM. This parameter must be set according to the SDRAM device specification.
After initialization, as soon as this field is modified and self refresh mode is activated, the Extended Mode Register of the
SDRAM device is accessed automatically and its TCSR parameter value is updated before entry in self refresh mode.
This field is transmitted to the SDRAM during initialization to specify whether only one quarter, one half or all banks of the
SDRAM array are enabled. Disabled banks are not refreshed in self refresh mode. This parameter must be set according to the
SDRAM device specification.
After initialization, as soon as this field is modified and self refresh mode is activated, the Extended Mode Register of the
SDRAM device is accessed automatically and its PASR parameter value is updated before entry in self refresh mode.
Low Power Register
Time to Define when Low Power Mode Is Enabled
The SDRAMC activates the SDRAM low power mode immediately after the end of the last transfer.
The SDRAMC activates the SDRAM low power mode 64 clock cycles after the end of the last transfer.
The SDRAMC activates the SDRAM low power mode 128 clock cycles after the end of the last transfer.
