Memory Map and Registers
Addresses: GPIOA_PPMODE – F140h base + 9h offset = F149h
9.2.11 GPIO Raw Data Register (GPIOx_RAWDATA)
This read-only register gives the DSP direct access to the logic values on each GPIO pin,
even when pins are not in GPIO mode. Values are not clocked and are subject to change
at any time. Read several times to ensure a stable value.
Addresses: GPIOA_RAWDATA – F140h base + Ah offset = F14Ah

Open-drain mode can be used to tri-state any pin on the GPIO
port without switching that pin to input mode. This capability is
useful for some applications, including a keypad interface.
