LS1043A, Reset configuration word (RCW) source Query

[logeshs]

Hi

In LS1043A, we are using NOR as the Boot Memory. To chose NOR as the RCW source in boot strap setting we need to set as mentioned in the 4.4.5.1 Reset configuration word (RCW) source of reference Manual. As per our configuration say suppose cfg_rcw_src bits are : 0_0001_0101. Please confim which is the LSB bit in the binary sequence.

Thanks

Have a great day,

The cfg_rcw_src[0:8] are multiplexed on the IFC_AD[8:15], IFC_CLE pins. In the manual values the least significant bit corresponds to the cfg_rcw_src[8]. For cfg_rcw_ = 0_0001_0101, on power-on reset the IFC_AD[8] pin has to be pulled down while the IFC_CLE pin has to be pulled up (the LS bit is ‘1’).
