This register controls the enable or disable of the combined pullup/pulldown
cell (0 = enabled, 1 = disabled). When enabling the cell, the user must set the
corresponding bit in PU_PD_SEL_2 to select either a pullup or a pulldown. The
pinout documentation in SPRS231 must 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.
