Bits 31:0 Gx_IOy: Gx_IOy channel mode
These bits are set and cleared by software to configure the Gx_IOy as a channel I/O.
0: Gx_IOy unused
1: Gx_IOy used as channel
Note: These bits must not be modified when an acquisition is ongoing.
During the acquisition phase and even if the TSC peripheral alternate function is not
enabled, as soon as the TSC_IOCCR bit is set, the corresponding GPIO analog switch
is automatically controlled by the touch sensing controller.
