14.4 XTAL and RTCX Printed Circuit Board (PCB) layout guidelines
The crystal should be connected on the PCB as close as possible to the oscillator input
and output pins of the chip. Take care that the load capacitors C
x1
, C
x2
, and C
x3
in case of
third overtone crystal usage have a common ground plane. The external components
must also be connected to the ground plain. Loops must be made as small as possible in
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.
14.5 Standard I/O pin configuration
Figure 25
shows the possible pin modes for standard I/O pins with analog input function:
Digital output driver: Open-drain mode enabled/disabled
Digital input: Pull-up enabled/disabled
Digital input: Pull-down enabled/disabled
Digital input: Repeater mode enabled/disabled
Analog input
The default configuration for standard I/O pins is input with pull-up enabled. The weak
MOS devices provide a drive capability equivalent to pull-up and pull-down resistors.
