Description
RESET/PIO0_0
yes
I
I; PU
RESET — External reset input with 20 ns glitch filter. A LOW-going
pulse as short as 50 ns on this pin resets the device, causing I/O
ports and peripherals to take on their default states, and processor
execution to begin at address 0.
I/O
-
PIO0_0 — General purpose digital input/output pin with 10 ns glitch
filter.
PIO0_1/CLKOUT/
CT32B0_MAT2/
USB_FTOGGLE
yes
I/O
I; PU
PIO0_1 — General purpose digital input/output pin. A LOW level on
this pin during reset starts the ISP command handler or the USB
device enumeration (USB on LPC1342/43 only, see description of
PIO0_3).
O-
CLKOUT — Clockout pin.
O-
CT32B0_MAT2 — Match output 2 for 32-bit timer 0.
O-
USB_FTOGGLE — USB 1 ms Start-of-Frame signal (LPC1342/43
only).
PIO0_2/SSEL0/
CT16B0_CAP0
I/O
I; PU
PIO0_2 — General purpose digital input/output pin.
I/O
-
SSEL0 — Slave select for SSP0.
I-
CT16B0_CAP0 — Capture input 0 for 16-bit timer 0.
PIO0_3/USB_VBUS
14[3] yes
I/O
I; PU
PIO0_3 — General purpose digital input/output pin. LPC1342/43
only: A LOW level on this pin during reset starts the ISP command
handler, a HIGH level starts the USB device enumeration.
I-
USB_VBUS — Monitors the presence of USB bus power
(LPC1342/43 only).
PIO0_4/SCL
15[4] yes
I/O
I; IA
PIO0_4 — General purpose digital input/output pin (open-drain).
I/O
-
SCL — I2C-bus clock input/output (open-drain). High-current sink
only if I2C Fast-mode Plus is selected in the I/O configuration
register.
PIO0_5/SDA
16[4] yes
I/O
I; IA
PIO0_5 — General purpose digital input/output pin (open-drain).
I/O
-
SDA — I2C-bus data input/output (open-drain). High-current sink
only if I2C Fast-mode Plus is selected in the I/O configuration
register.
PIO0_6/
USB_CONNECT/
SCK0
I/O
I; PU
PIO0_6 — General purpose digital input/output pin.
O-
USB_CONNECT — Signal used to switch an external 1.5 k
Ω
resistor under software control. Used with the SoftConnect USB
feature (LPC1342/43 only).
I/O
-
SCK0 — Serial clock for SSP0.
PIO0_7/CTS
I/O
I; PU
PIO0_7 — General purpose digital input/output pin (high-current
output driver).
I-
CTS — Clear To Send input for UART.
PIO0_8/MISO0/
CT16B0_MAT0
I/O
I; PU
PIO0_8 — General purpose digital input/output pin.
I/O
-
MISO0 — Master In Slave Out for SSP0.
O-
CT16B0_MAT0 — Match output 0 for 16-bit timer 0.
