Table 82 GPIO Power Domain Registers
The function of each GPIO is controlled using the GPn_FN registers defined in Table 83. Note that
the selected function also depends on the associated GPn_DIR field described in Table 80.
See also Section 21.2 for additional details of each GPIO function, including the applicable de-
bounce times for GPIO input functions.
The Touch Panel controller must be disabled if using GPIO13 to GPIO16 as GPIO functions. Note
that, when the Touch Panel controller is enabled, GPIO13 to GPIO16 must be tri-stated using the
GPn_ENA register bits (see Table 80).
