R — Function reserved.
U4_RXD — Receiver input for USART4.
I2C0_SCL — I
specialized I
P5[4] — General purpose digital input/output pin.
U0_OE — RS-485/EIA-485 output enable signal for UART0.
R — Function reserved.
T3_MAT3 — Match output for Timer 3, channel 3.
U4_TXD — Transmitter output for USART4 (input/output in
smart card mode).
JTAG_TDO (SWO) — Test Data Out for JTAG interface. Also
used as Serial wire trace output.
JTAG_TDI — Test Data In for JTAG interface.
JTAG_TMS (SWDIO) — Test Mode Select for JTAG interface.
Also used as Serial wire debug data input/output.
JTAG_TRST — Test Reset for JTAG interface.
JTAG_TCK (SWDCLK) — Test Clock for JTAG interface. This
clock must be slower than 1 /6 of the CPU clock (CCLK) for the
JTAG interface to operate. Also used as serial wire clock.
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. This pin includes
a 20 ns input glitch filter.
Reset status output. A LOW output on this pin indicates that the
device is in the reset state, for any reason. This reflects the
RESET input pin and all internal reset sources.
RTC_ALARM — RTC controlled output. This is a 1.8 V pin. It
goes HIGH when a RTC alarm is generated.
Input to the RTC 32 kHz ultra-low power oscillator circuit.
Output from the RTC 32 kHz ultra-low power oscillator circuit.
USB_D2 — USB port 2 bidirectional D line.
RTC power supply: 3.3 V on this pin supplies power to the
RTC.
