4.1.2.1. local_reset_req for QDR-IV

Local reset request. Output signal from local_reset_combiner
Table 40.  Interface: local_reset_reqInterface type: Conduit
Port Name Direction Description
local_reset_req Input Signal from user logic to request the memory interface to be reset and recalibrated. Reset request is sent by transitioning the local_reset_req signal from low to high, then keeping the signal at the high state for a minimum of 2 EMIF core clock cycles, then transitioning the signal from high to low. local_reset_req is asynchronous in that there is no setup/hold timing to meet, but it must meet the minimum pulse width requirement of 2 EMIF core clock cycles.
