• Cycle number from the issuance of the WRITA 
command by this LSI until the completion of auto-
precharge in the SDRAM. 
Equivalent to the cycle number from the issuance 
of the WRITA command until the issuance of the 
ACTV command. Confirm that how many cycles 
are required between the WRITA command 
receive in the SDRAM and the auto-precharge 
activation, referring to each SDRAM data sheet. 
And set the cycle number so as not to exceed the 
cycle number specified by this bit. 
• Cycle number from the issuance of the WRIT 
command until the issuance of the PRE 
command. This is the case when accessing 
another low address in the same bank in bank 
active mode.

Description added 
The data cycle is the same as that in a normal space 
access. 
The delay cycles specified by SW[1:0] are inserted 
between the Ta3 and T1 cycles. The delay cycles specified 
by HW[1:0] are added after the T2 cycle.
