9.4.49 PINCTRL Bank 1 Data Input Register (HW_PINCTRL_DIN1)
The current value of all bank 1 pins may be read from the PINCTRL Bank 1 Data Input
Register.
HW_PINCTRL_DIN1: 0x910
HW_PINCTRL_DIN1_SET: 0x914
HW_PINCTRL_DIN1_CLR: 0x918
HW_PINCTRL_DIN1_TOG: 0x91C
This register reflects the current values of all the bank 1 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.

Empty Description.
Each bit in this read-only register corresponds to one of the 29 pins in bank 0. The current state of each pin
in bank 0, synchronized to HCLK, may be read here.
Each bit in this read-only register corresponds to one of the 32 pins in bank 1. The current state of each pin
in bank 1, synchronized to HCLK, may be read here.
