LPC2210/2220

16/32-bit ARM microcontrollers with external memory interface

P2.26/D26/

BOOT0

13[5]

F4[5]

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[5]

F1[5]

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 16-bit memory on CS0 for boot.

P2.28/D28

17[5]

G2[5]

I/O

D28 — External memory data line 28.

P2.29/D29

18[5]

G1[5]

I/O

D29 — External memory data line 29.

P2.30/D30/

AIN4

19[2]

G3[2]

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[2]

G4[2]

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 — 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.
