14.2.14.7 Debug Data (DDATA[3:0])
Debug data signals (DDATA[3:0]) display captured processor addresses, data and breakpoint status.
These pins can also be configured as GPIO PDD[7:4].
14.2.14.8 Processor Status Outputs (PST[3:0])
PST[3:0] outputs indicate core status, as shown below in
with the processor clock; status is unrelated to the current bus transfer.
These pins can also be configured as GPIO PDD[3:0].
14.2.15 Test Signals
14.2.15.1 Test (TEST)
This input signal is reserved for factory testing only and should be connected to VSS to prevent
unintentional activation of test functions.
