NAPXA4...0 - Nap Exit Phase A. This field speci-
fies the number of SCK cycles during the first
phase for exiting NAP mode. It must satisfy:
NAPXA *
t
SCYCLE
t
NAPXA,MAX
Do not set this field to zero.
NAPX4...0 - Nap Exit Phase A plus B. This field specifies
the number of SCK cycles during the first plus second
phases for exiting NAP mode. It must satisfy:
NAPX *
t
SCYCLE
NAPXA *

NAPXB,MAX
Do not set this field to zero.
DQS - DQ Select. This field specifies the number of SCK
cycles (0 => 0.5 cycles, 1 => 1.5 cycles) between the
CMD pin framing sequence and the device selection
on DQ5...0. See Figure 48 - This field must be written
with a “1” for this RDRAM.
