3.1.1 Pin Arrangement (TQFP15-128pin)
Figure 1.
Note: The external pins shown below do not exist in the 128-pin package model.
PA0, PA1, PA2, PA3, PA6, PB0, PB1, PB2, PB3, PB4, PB5, PB6, PB7, A24, A25, WAKEUP
These internal signals except A24, A25, and WAKEUP are placed into high-impedance state after
an initial reset. Therefore, enables the pull-up resistors for these pins. Do not switch the A24 and
A25 port functions from the initial settings.
