Description
P2.18 — General purpose digital input/output pin.
D18 — External memory data line 18.
P2.19 — General purpose digital input/output pin.
D19 — External memory data line 19.
P2.20 — General purpose digital input/output pin.
D20 — External memory data line 20.
P2.21 — General purpose digital input/output pin.
D21 — External memory data line 21.
P2.22 — General purpose digital input/output pin.
D22 — External memory data line 22.
P2.23 — General purpose digital input/output pin.
D23 — External memory data line 23.
P2.24 — General purpose digital input/output pin.
D24 — External memory data line 24.
P2.25 — General purpose digital input/output pin.
D25 — External memory data line 25.
P2.26 — General purpose digital input/output pin.
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.
P2.27 — General purpose digital input/output pin.
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.
P2.28 — General purpose digital input/output pin.
D28 — External memory data line 28.
P2.29 — General purpose digital input/output pin.
D29 — External memory data line 29.
P2.30 — General purpose digital input/output pin.
D30 — External memory data line 30.
AIN4 — ADC, input 4. This analog input is always connected to its pin.
P2.31 — General purpose digital input/output pin.
D31 — External memory data line 31.
AIN5 — ADC, 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.
