This register controls the enable or disable of the combined pullup/pulldown
cell (0 = enabled, 1 = disabled). When enabling the cell, it is assumed that the
user has cleared or set the corresponding bit in PU_PD_SEL_3 to select a
pullup or a pulldown. The pinout section in the Application Processor Data
Manual (SPRS231) should be consulted to determine whether a pullup or
pulldown exists on the specified I/O. COMP_MODE_CTRL_0 must be
programmed to 0xEAEF, so that the programming is taken into account in the
corresponding tactical cell.
