Description
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 16-bit memory on CS0 for boot.

D29 —
External memory data line 29.
D30 —
External memory data line 30.
AIN4 —
A/D converter, input 4. This analog input is always
connected to its pin.
D31 —
External memory data line 31.
AIN5 —
A/D converter, input 5. This analog input is always
connected to its pin.
Port 3 —
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.
