In conjunction with the GCTL_DS register, this register determines whether a weak pull-down on each I/O pin should be
engaged. Firmware should not enable WPU and WPD simultaneously on a given I/O. A weak pull-up or weak pull-down takes
about 5 µs to be effective at the pads.
59:0 WPD[59:0] When set, a weak pull-down is connected for the pin associated with the corresponding GPIO #.
