Description
P4[23] — General purpose digital input/output pin.
A23 — External memory address line 23.
RXD2 — Receiver input for UART2.
MOSI1 — Master Out Slave In for SSP1.
P4[24] — General purpose digital input/output pin.
OE — LOW active Output Enable signal.
P4[25] — General purpose digital input/output pin.
WE — LOW active Write Enable signal.
P4[26] — General purpose digital input/output pin.
BLS0 — LOW active Byte Lane select signal 0.
P4[27] — General purpose digital input/output pin.
BLS1 — LOW active Byte Lane select signal 1.
P4 [28] — General purpose digital input/output pin.
BLS2 — LOW active Byte Lane select signal 2.
MAT2[0] — Match output for Timer 2, channel 0.^[19]
LCDVD[6]/LCDVD[10]/LCDVD[2] — LCD data.^[19]
TXD3 — Transmitter output for UART3.
P4[29] — General purpose digital input/output pin.
BLS3 — LOW active Byte Lane select signal 3.
MAT2[1] — Match output for Timer 2, channel 1.^[19]
LCDVD[7]/LCDVD[11]/LCDVD[3] — LCD data.^[19]
RXD3 — Receiver input for UART3.
P4[30] — General purpose digital input/output pin.
CS0 — LOW active Chip Select 0 signal.
P4[31] — General purpose digital input/output pin.
CS1 — LOW active Chip Select 1 signal.
ALARM — RTC controlled output. This is a 1.8 V pin. It goes HIGH when
a RTC alarm is generated.
USB_D−2 — USB port 2 bidirectional D− line.
DBGEN — JTAG interface control signal. Also used for boundary
scanning.
TDO — Test Data out for JTAG interface.
TDI — Test Data in for JTAG interface.
TMS — Test Mode Select for JTAG interface.
TRST — Test Reset for JTAG interface.
TCK — Test Clock for JTAG interface. This clock must be slower than ¹â„₆
of the CPU clock (CCLK) for the JTAG interface to operate.
RTCK — JTAG interface control signal.
Note: LOW on this pin while RESET is LOW enables ETM pins (P2[9:0])
to operate as Trace port after reset.
RSTOUT — This is a 1.8 V pin. LOW on this pin indicates LPC2470
being in Reset state.
