LPC11Cx2/Cx4
32-bit ARM Cortex-M0 microcontroller
order to keep the noise coupled in via the PCB as small as possible. Also parasitics
should stay as small as possible. Values of C
x1
and C
x2
should be chosen smaller
accordingly to the increase in parasitics of the PCB layout.
11.4 Standard I/O pad configuration
Figure 25 shows the possible pin modes for standard I/O pins with analog input function:
• Digital output driver
• Digital input: Pull-up enabled/disabled
• Digital input: Pull-down enabled/disabled
• Digital input: Repeater mode enabled/disabled
• Analog input
