Programmable Registers
9.4.55 PINCTRL Bank 2 Data Output Enable Register
The PINCTRL Bank 2 Output Enable Register controls the output enable signal for all pins
in bank 2 that are configured for GPIO mode.
HW_PINCTRL_DOE2: 0xb20
HW_PINCTRL_DOE2_SET: 0xb24
HW_PINCTRL_DOE2_CLR: 0xb28
HW_PINCTRL_DOE2_TOG: 0xb2C
For pins in bank 2 that are configured as GPIOs, a 1 in this register will enable the
corresponding bit value from HW_PINCTRL_DOUTxx register to be driven out the pin,
and a 0 in this register will disable the corresponding driver.
Address:
