Programmable Registers
Address:
Re-
9.4.48 PINCTRL Bank 0 Data Input Register (HW_PINCTRL_DIN0)
The current value of all bank 0 pins may be read from the PINCTRL Bank 0 Data Input
Register.
HW_PINCTRL_DIN0: 0x900
HW_PINCTRL_DIN0_SET: 0x904
HW_PINCTRL_DIN0_CLR: 0x908
HW_PINCTRL_DIN0_TOG: 0x90C
This register reflects the current values of all the bank 0 pins. The register accurately reflects
the state of the pin regardless of the setting of the HW_PINCTRL_MUXSELx or
HW_PINCTRL_DOEx registers, but generally, if it is desired to use a pin as a general
purpose input, the pin's two bits in the HW_PINCTRL_MUXSELx register should be set
to 3 (GPIO mode) and the pin's bit in the HW_PINCTRL_DOEx register should be set to
0 (disabled) to insure that the chip is not driving the pin.
