GPIO Muxed Pins

Table 4-6 lists the GPIO muxed pins. The default mode for each GPIO pin is the GPIO function, except GPIO35 and GPIO37, which default to TDI and TDO, respectively. Secondary functions can be selected by setting both the GPyGMUXn.GPIOz and GPyMUXn.GPIOz register bits. The GPyGMUXn register should be configured before the GPyMUXn to avoid transient pulses on GPIOs from alternate mux selections. Columns that are not shown and blank cells are reserved GPIO Mux settings.

NOTE

GPIO20, GPIO21, and GPIO41 to GPIO55 are not available on any packages. Boot ROM enables pullups on these pins. For more details, see Section 4.5.

TDI I JTAG Test Data Input (TDI) - TDI is the default mux selection for the pin. The internal pullup is disabled by default. The internal pullup should be enabled or an external pullup added on the board if this pin is used as JTAG TDI to avoid a floating input. GPIO35/TDI GPIO35/TDI GPIO35/TDI GPIO35/TDI
TDO O JTAG Test Data Output (TDO) - TDO is the default mux selection for the pin. The internal pullup is disabled by default. The TDO function will be in a tri-state condition when there is no JTAG activity, leaving this pin floating; the internal pullup should be enabled or an external pullup added on the board to avoid a floating GPIO input.

VFBSW - Internal DC-DC regulator feedback signal. If the internal DC-DC regulator is used, tie this pin to the node where L(VSW) connects to the VDD rail (as close as possible to the device). GPIO22_VFBSW GPIO22_VFBSW GPIO22_VFBSW GPIO22_VFBSW
