: Performing a serial data output operation requires that a command to transfer data from DRAM be issued.
If this command has not been issued, the STCK and STDAT pins will not output the clock and data signals, even if the STREQ goes
high.

Notes: The typical values shown apply when the frequency of the clock input to the CKIN pin is 16.9344 MHz.

The fsck clock frequency can also be set to 2.1168 or 1.0584 MHz (typical). The values of T3 to T7 will be, in that case, 2
or 4 times the values shown.
x
When the STREQ pin is in input mode, the WOK, OVF, and CNTOK pins can be used instead of the STREQ, STCK, and
SDAT pins. The timing specifications in this case are the same as those shown above.
