Programmable Registers
9.4.40 PINCTRL Bank 4 Pull Up Resistor Enable Register
The PINCTRL Bank 4 PULL Register enables/disables the internal pull up resistors for
those pins in bank 4 which support this operation.
HW_PINCTRL_PULL4: 0x640
HW_PINCTRL_PULL4_SET: 0x644
HW_PINCTRL_PULL4_CLR: 0x648
HW_PINCTRL_PULL4_TOG: 0x64C
The Pull register enables/disables integrated on-chip pull up resistors or pad keepers for the
pins.
