DESCRIPTION
CK0
Clock Inputs
The system clock input. All other inputs are registered to the SDRAM on
the rising edge of CLK
CKE0
Clock Enable
Controls internal clock signal and when deactivated, the SDRAM will be
one of the states among power down, suspend or self refresh
/S0 ~ /S3
Chip Select
Enables or disables all inputs except CK, CKE and DQM
BA0, BA1
SDRAM Bank Address
Selects bank to be activated during /RAS activity
Selects bank to be read/written during /CAS activity
A0 ~ A12
Address
Row Address : RA0 ~ RA12, Column Address : CA0 ~ CA9, CA11
Auto-precharge flag : A10
