Signal Primary Functions
Development Serial
Input
DSI
This internally-synchronized signal provides data input for the serial
communication port to the BDM module.
I
Development Serial
Output
DSO
This internally-registered signal provides serial output communication
for BDM module responses.
O
Debug Data
DDATA[3:0]
Display captured processor data and breakpoint status. The CLKOUT
signal can be used by the development system to know when to
sample DDATA[3:0].
O
Processor Status
Outputs
PST[3:0]
Indicate core status, as shown in Table 16. Debug mode timing is
synchronous with the processor clock; status is unrelated to the
current bus transfer. The CLKOUT signal can be used by the
development system to know when to sample PST[3:0].
