Description
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 LPC2364/66/68
being in Reset state.
Note: This pin is available in LPC2364FBD100, LPC2366FBD100, and
LPC2368FBD100 devices only (LQFP package).
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.
ground: 0 V reference.
analog ground: 0 V reference. This should nominally be the same voltage
as V
3.3 V supply voltage: This is the power supply voltage for the I/O ports.
3.3 V DC-to-DC converter supply voltage: This is the supply voltage for
the on-chip DC-to-DC converter only.
analog 3.3 V pad supply voltage: This should be nominally the same
voltage as V
voltage is used to power the ADC and DAC.
ADC reference: This should be nominally the same voltage as V
should be isolated to minimize noise and error. Level on this pin is used as
a reference for ADC and DAC.
RTC pin power supply: 3.3 V on this pin supplies the power to the RTC
peripheral.
