7.2.2 General-Purpose I/O (GPIO)
Figure 7
shows the commands to write, read and control the
general-purpose I/O port pins, GEN_IO_0, GEN_IO_1, GE-
N_IO_2, and GEN_IO_3.
All general-purpose I/O pins can be programmed as inputs
or outputs as shown in
Table 4
. The GEN_IO_0 and GE-
N_IO_1 pins provide an additional capability for program-
mable wake-up.
