LPC2212/2214

Single-chip 16/32-bit ARM microcontrollers

P0[30]/AIN3/EINT3/

CAP0[0]

33

I

AIN3 — ADC, input 3. This analog input is always connected to its pin.

I

EINT3 — External interrupt 3 input.

I

CAP0[0] — Capture input for Timer 0, channel 0.

P1[0] to P1[31]

I/O

Port 1 is a 32-bit bidirectional I/O port with individual direction controls for

each bit. The operation of port 1 pins depends upon the pin function selected

via the Pin Connect Block.

Pins 2 through 15 of port 1 are not available.

P1[0]/CS0

91

O

LOW-active Chip Select 0 signal.

(Bank 0 addresses range 0x8000 0000 to 0x80FF FFFF)

P1[1]/OE

90

O

LOW-active Output Enable signal.

P1[16]/TRACEPKT0

34

O

Trace Packet, bit 0. Standard I/O port with internal pull-up.

P1[17]/TRACEPKT1

24

O

Trace Packet, bit 1. Standard I/O port with internal pull-up.

P1[18]/TRACEPKT2

15

O

Trace Packet, bit 2. Standard I/O port with internal pull-up.

P1[19]/TRACEPKT3

7

O

Trace Packet, bit 3. Standard I/O port with internal pull-up.

P1[20]/TRACESYNC

102

O

Trace Synchronization; standard I/O port with internal pull-up.

Note: LOW on this pin while RESET is LOW, enables pins P1[25:16] to

operate as Trace port after reset.

P1[21]/PIPESTAT0

95

O

Pipeline Status, bit 0. Standard I/O port with internal pull-up.

P1[22]/PIPESTAT1

86

O

Pipeline Status, bit 1. Standard I/O port with internal pull-up.

P1[23]/PIPESTAT2

82

O

Pipeline Status, bit 2. Standard I/O port with internal pull-up.

P1[24]/TRACECLK

70

O

Trace Clock. Standard I/O port with internal pull-up.

P1[25]/EXTIN0

60

I

External Trigger Input. Standard I/O with internal pull-up.

P1[26]/RTCK

52

I/O

Returned Test Clock output. Extra signal added to the JTAG port. Assists

debugger synchronization when processor frequency varies. Bidirectional pin

with internal pull-up.

Note: LOW on this pin while RESET is LOW, enables pins P1[31:26] to

operate as Debug port after reset.

P1[27]/TDO

144

O

Test Data out for JTAG interface.

P1[28]/TDI

140

I

Test Data in for JTAG interface.

P1[29]/TCK

126

I

Test Clock for JTAG interface. This clock must be slower than 1⁄6 of the CPU

clock (CCLK) for the JTAG interface to operate.

P1[30]/TMS

113

I

Test Mode Select for JTAG interface.

P1[31]/TRST

43

I

Test Reset for JTAG interface.

P2[0] to P2[31]

I/O

Port 2 is a 32-bit bidirectional I/O port with individual direction controls for

each bit. The operation of port 2 pins depends upon the pin function selected

via the Pin Connect Block.

P2[0]/D0

98

I/O

External memory data line 0.

P2[1]/D1

105

I/O

External memory data line 1.

P2[2]/D2

106

I/O

External memory data line 2.

P2[3]/D3

108

I/O

External memory data line 3.

P2[4]/D4

109

I/O

External memory data line 4.

P2[5]/D5

114

I/O

External memory data line 5.

P2[6]/D6

115

I/O

External memory data line 6.
