6.9.4 Peripheral Pins Used by Bootloaders
Table 6-14 shows the GPIO pins used by each peripheral bootloader. This device supports two sets of
GPIOs for each mode, as shown in Table 6-14.

The USB Bootloader will switch the clock
source to the external crystal oscillator (X1
and X2 pins). A 20-MHz crystal should be
present on the board if this boot mode is
selected.
