Description
DRAM function pins not associated with Chip Select.
DRAM inputs, re-driven only when Chip Select is LOW.
DRAM Chip Select signals. These pins initiate DRAM
address/command decodes, and as such at least one will
be LOW when a valid address/command is present. The
register can be programmed to re-drive all D-inputs only
(CSGATEEN = HIGH) when at least one Chip Select
input is LOW. DCS2 and DCS3 are not re-driven and can
be left open-circuit to default HIGH by means of its
internal pull-up resistors.
Outputs of the register, valid after the specified clock
count and immediately following a rising edge of the
clock.
Parity input for the D0 to D21 inputs. Arrives one clock
cycle after the corresponding data input.
identified associated with the address and/or command
inputs. PTYERR will be active for two clock cycles, and
delayed by an additional clock cycle for compatibility with
final parity out timing on the industry-standard DDR2
register with parity (in JEDEC definition).
