PDI_CLK
This pull-up resistor makes sure that reset does not go low
unintended. When the PDI programming and debugging is used,
the reset line is used as clock. The reset pull-up should be 10k

or weaker, or be removed.
Any reset capacitors should be removed if PDI programming
and debugging is used. Other external reset sources should be
disconnected.
