P0.3/PLAO[9]/TCK
The default value of this pin depends on the level of P0.0/BM. If P0.0/BM =
0, this pin defaults to a general purpose input. If P0.0/BM = 1, this pin
defaults to a JTAG test data clock pin. This is a multifunction pin as follows:
General-Purpose Input and Output Port 0.3.
Programmable Logic Array Output Element 9.
Test Clock, JTAG Test Port Clock Input. Debug and download access. When
debugging the part via JTAG, this pin must not be toggled by user code
and the GP0CON/GP0DAT register bits affecting this pin must not be
changed.
