Direct RDRAM
Revision 0.7 September 1998
TARGET
The SCK clock is also used for sampling data on RSL inputs
in one situation. Figure 47 shows the PDN and NAP exit
sequences. If the PSX field of the INIT register is zero (see
Figure 27), then the PDN and NAP exit sequences are broad-
cast; i.e. all RDRAMs that are in PDN or NAP will perform
the exit sequence. If the PSX field of the INIT register is
one, then the PDN and NAP exit sequences are directed; i.e.
only one RDRAM that is in PDN or NAP will perform the
exit sequence.
The address of that RDRAM is specified on the DQA[5:0]
bus in the set hold window t

arouond the rising edge of
SCK. This is shown in Figure Figure. The SCK timing point
is measured at the 50% level, and the DQA[5:0] bus signals
are measured at the V
REF
level.
