9.4.37 PINCTRL Bank 1 Pull Up Resistor Enable Register
The PINCTRL Bank 1 PULL Register enables/disables the internal pull up resistors for
those pins in bank 1 which support this operation.
HW_PINCTRL_PULL1: 0x610
HW_PINCTRL_PULL1_SET: 0x614
HW_PINCTRL_PULL1_CLR: 0x618
HW_PINCTRL_PULL1_TOG: 0x61C
The Pull register enables/disables integrated on-chip pull up resistors or pad keepers for the
pins.
