UHPI_HA[15:0] (Input Only)
(1) When using the UHPI in non-multiplexed mode, ensure EM_D[31:16] are configured as inputs so that these pins may be used as
UHPI_HA[15:0]. To ensure this, you must set the CFGHPI.NMUX bit to a '1' before the EMIF SDRAM initialization completes;
otherwise, a drive conflict will occur. [The EMIF bus parking function drives the data bus in between accesses.]
