Evaluation board has 100k resistors.
Some pins are connected directly to ground (mostly hardware configuration ones).
Correction: this one is about input analogue pins. Internally they seem to have 1M resistor (at least from the spec). What's the point of 270R?
Also different pins have different pull up/down resistors in evaluation schematics (some 10k some 100k some none at all). If I didn't have an evaluation schematics where can I find information on how to properly route everything from data sheet?
I am using mine in hardware mode. Is pull up resistor of 10k okay for between VDRIVE and pin for all configuration pins (!WR/BURST for instance has 100k resistor, SER/!PAR has 10k resistor)?
I am checking on this and get back to you soon.
The 100k resistors on the digital lines are pull downs so that these lines will not keep floating when not in use. The 270 ohm on the input is a sense resistor for voltage conversion. This is typically for a 4 to 20mA application to convert to 1V to 5V range.
