SET-UP, CONFIGURATION & RESET PINS
Regardless of the mode of operation, (Quad or Dual), the following inputs
must be always be used. These inputs must be set-up with respect to master
reset as they are latched during this time.
WDDR – Write Port DDR/SDR selection
RDDR – Read Port DDR/SDR selection
MD – Mode Selection
OW – Output width
IW – Input Width
FSEL[1:0] – Flag offset default values
IOSEL – I/O Level Selection
PFM– Programmable Flag Mode
FWFT/SI – First word Fall Through or IDT Standard mode
QUAD MODE
The following inputs/ outputs should be used when Mux mode is selected
by the user:
