D26 —
External memory data line 26.
BOOT0 —
While RESET is LOW, together with BOOT1 controls booting and
internal operation. Internal pull-up ensures HIGH state if pin is left
unconnected.
D27 —
External memory data line 27.
BOOT1 —
While RESET is LOW, together with BOOT0 controls booting and
internal operation. Internal pull-up ensures HIGH state if pin is left
unconnected.
BOOT1:0 = 00 selects 8-bit memory on CS0 for boot.
BOOT1:0 = 01 selects 16-bit memory on CS0 for boot.
BOOT1:0 = 10 selects 32-bit memory on CS0 for boot.
BOOT1:0 = 11 selects internal flash memory.

AIN5 —
ADC, input 5. This analog input is always connected to its pin.
Port 3 is a 32-bit bidirectional I/O port with individual direction controls for
each bit. The operation of port 3 pins depends upon the pin function selected
via the Pin Connect Block.
