Description
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.
MAT2[0] — Match output for Timer 2, channel 0.
TXD3 — Transmitter output for UART3.
P4[29] — General purpose digital input/output pin.
MAT2[1] — Match output for Timer 2, channel 1.
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 scan.
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
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 3.3 V pin. LOW on this pin indicates UM10237 being in
Reset state.
external reset input: A LOW 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. TTL with hysteresis, 5 V tolerant.
Input to the oscillator circuit and internal clock generator circuits.
Output from the oscillator amplifier.
Input to the RTC oscillator circuit.
Output from the RTC oscillator circuit.
