SDRAMC Low Power Register
LPCB | Low-power Configuration Bits 0 (DISABLED): Low Power Feature is inhibited: no Power-down, Self-refresh or Deep Power-down command is issued to the SDRAM device. 1 (SELF_REFRESH): The SDRAMC issues a Self-refresh command to the SDRAM device, the SDCK clock is deactivated and the SDCKE signal is set low. The SDRAM device leaves the Self Refresh Mode when accessed and enters it after the access. 2 (POWER_DOWN): The SDRAMC issues a Power-down Command to the SDRAM device after each access, the SDCKE signal is set to low. The SDRAM device leaves the Power-down Mode when accessed and enters it after the access. 3 (DEEP_POWER_DOWN): The SDRAMC issues a Deep Power-down command to the SDRAM device. This mode is unique to low-power SDRAM. |
PASR | Partial Array Self-refresh (only for low-power SDRAM) |
TCSR | Temperature Compensated Self-Refresh (only for low-power SDRAM) |
DS | Drive Strength (only for low-power SDRAM) |
TIMEOUT | Time to Define When Low-power Mode Is Enabled 0 (LP_LAST_XFER): The SDRAMC activates the SDRAM low-power mode immediately after the end of the last transfer. 1 (LP_LAST_XFER_64): The SDRAMC activates the SDRAM low-power mode 64 clock cycles after the end of the last transfer. 2 (LP_LAST_XFER_128): The SDRAMC activates the SDRAM low-power mode 128 clock cycles after the end of the last transfer. |
