GPIOs — I2C Registers
SLVS606C – SEPTEMBER 2005 – REVISED FEBRUARY 2007
The I2C registers that control GPIO-related functions are shown below. The HEX address for each register is
shown by the register name, together with the R or W functionality for the register bits. Shaded values indicate
default initial power-up values.
