Table A–9 Bank Set Timing Register B
Field Name Type Description
<15:14> Reserved MBZ —
<13:11> S8_WHOLD0COL RW, 1 Write hold time from column address. Used only for
the first data when starting in page mode. Write
data is valid with the column address and is held
valid S8_WHOLD0COL + 2 cycles after the column
address.
.
<10:8> S8_WHOLD0ROW RW, 1 Write hold time from row address. Hold time of
first write data from first row address. The first
write data is valid with the row address, and is held
valid S8_WHOLD0ROW + 2 cycles after the row
address. Used when not starting in page mode. A
programmed value of zero is illegal.
.
<7:6> S8_TCP RW, 1 CAS precharge (t
CP
). Delay from b0_cas<1:0>_l
deassertion to the next assertion of b0_cas<1:0>_l in
page mode.
.
<5:3> S8_WTCAS RW, 1 Write CAS width (t
CAS
). Used on write transactions
to generate the b0_cas<1:0>_l deassertion from the
assertion of b0_cas<1:0>_l.
Note: S8_WTCAS and S8_TCP should be
programmed such that their sum is
5.
.
<2:0> S8_RTCAS RW, 1 Read CAS width (t
CAS
). Used on read transactions
to generate the b0_cas<1:0>_l deassertion from the
assertion of b0_cas<1:0>_l.
Note: S8_RTCAS and S8_TCP should be
programmed such that their sum is
5.
