(18) DCU (debug control unit)
An on-chip debug function that uses the JTAG (Joint Test Action Group) communication specifications is provided.
Switching between the normal port function and on-chip debugging function is done with the control pin input
level and the OCDM register.
(19) Ports
The following general-purpose port functions and control pin functions are available.
