RCW field IFC_GRP_E1_EXT in LS1046

[Urmila_123]

hi all,

It is mentioned in LS1046ARM that if the RCW field IFC_GRP_E1_EXT is set as 001, A19 can be used as IFC_CS_B[1]/GPIO2_10 and A20 can be used asIFC_CS_B[2]/GPIO2_11. Is there any other field separating GPIO functionality from IFC_CS_B[0/1]? or Can we simply use these lines as GPIOs by making IFC_GRP_E1_EXT  001? Please Clarify.

Thanks & Regards

Urmila P.

IFC_CS_B[0] does not have alternate functions.

For all possible alternate functions of the IFC signals refer to the LS1046A Reference Manual, Table 3-9. IFC signal configuration.
