12
I/O External memory data line 25.
P2[26]/D26/BOOT0
13
I/O D26 — External memory data line 26.
I
BOOT0 — While RESET is LOW, together with BOOT1 controls booting and
internal operation. Internal pull-up ensures HIGH state if pin is left
unconnected.
P2[27]/D27/BOOT1
16
I/O D27 — External memory data line 27.
I
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.
P2[28]/D28
17
I/O External memory data line 28.
P2[29]/D29
18
I/O External memory data line 29.
P2[30]/D30/AIN4
19
I/O D30 — External memory data line 30.
I
AIN4 — ADC, input 4. This analog input is always connected to its pin.
P2[31]/D31/AIN5
20
I/O D31 — External memory data line 31.
I
AIN5 — ADC, input 5. This analog input is always connected to its pin.
P3[0] to P3[31]
I/O 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.
P3[0]/A0
89
O External memory address line 0.
P3[1]/A1
88
O External memory address line 1.
P3[2]/A2
87
O External memory address line 2.
