LPC11D14
32-bit ARM Cortex-M0 microcontroller
[2] RESET functionality is not available in Deep power-down mode. Use the WAKEUP pin to reset the chip and wake up from Deep
power-down mode. An external pull-up resistor is required on this pin for the Deep power-down mode.
[3] 5 V tolerant pad providing digital I/O functions with configurable pull-up/pull-down resistors and configurable hysteresis.
[4] I
2
C-bus pads compliant with the I
2
C-bus specification for I
2
C standard mode and I
2
C Fast-mode Plus.
[5] 5 V tolerant pad providing digital I/O functions with configurable pull-up/pull-down resistors, configurable hysteresis, and analog input.
When configured as a ADC input, digital section of the pad is disabled and the pin is not 5 V tolerant.
[6] When the system oscillator is not used, connect XTALIN and XTALOUT as follows: XTALIN can be left floating or can be grounded
(grounding is preferred to reduce susceptibility to noise). XTALOUT should be left floating.
