This register controls the selection of the pullup or pulldown (0 = pulldown, 1
= pullup). The pinout documentation (Application Processor Data Manual
(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 for this register to control the selection.
