Forum Post: RE: DM368 AEMIF's WE#

$

Hi Eason,

I am seeing the same phenomenon

EM_WE (pin J15) & EM_OE (pin J19), both pull-up to 3.3V through 10k resistor, are showing two different behaviours:     

EM_WE will "stuck" at around 2.2V after 3.3V supply voltage is applied, when the RESET# pin is still asserted (Seems like the pin is pulled down internally with 20k impedance??). The EM_WE will only rise to 3.3V after the RESET# is released.

EM_OE will rise to 3.3V once 3.3V supply voltage is applied, regardless of whether RESET# pin is released or not.  

Kindly advice if these is the characteristic of DM365/DM368 or have we done something wrong? 

Regards
