TD1204 EVB User guide mentions GP0 and GP1 as GPIO while they are in fact reserved.

On page 18 (Rev1.1) of the TD1204 EVB User Guide it is stated that pin 5 (GP0) and pin 7 (GP1) on the break-out header can be used as General Purpose Low-Power Digital I/O, while in fact the pins they connect to on the TD1204 are reserved.

These pins are connected internally to the RF chip and are not addressable from the MCU directly.

Their purpose is to control some RF-related functions, such as an external LNA or PA, and should be considered as reserved except in these very particular cases.
