Description
Refresh Control
Specifies whether to perform auto-refresh or self-
refresh when the RFSH bit is 1. When the RFSH bit is
1 and this bit is 1, self-refresh starts immediately.
When the RFSH bit is 1 and this bit is 0, auto-refresh
starts according to the contents that are set in
registers RTCSR, RTCNT, and RTCOR.
0: Auto-refresh is performed
1: Self-refresh is performed
Power-Down Mode
Specifies whether the SDRAM will enter the power-
down mode after the access to the SDRAM. With this
bit being set to 1, after the SDRAM is accessed, the
CKE signal is driven low and the SDRAM enters the
power-down mode.
0: The SDRAM does not enter the power-down mode
1: The SDRAM enters the power-down mode after
Bank Active Mode
Specifies to access whether in auto-precharge mode
(using READA and WRITA commands) or in bank
active mode (using READ and WRIT commands).
0: Auto-precharge mode (using READA and WRITA
1: Bank active mode (using READ and WRIT
Note: Bank active mode can be used only when

either the upper or lower bits of the CS3 space
are used. When both the CS2 and CS3 spaces
are set to SDRAM, specify the auto-precharge
mode.
