10.10 DSP56K TARGET SITE DEBUG SYSTEM REQUIREMENTS
A typical DSP56K debug environment consists of a target system where the DSP56K re-
sides in the user defined hardware. The debug serial port interfaces to the external com-
mand controller over a 6-wire link which includes the 4 OnCE wires, a ground, and a reset
wire. The reset wire is optional and is only used to reset the DSP56K and its associated
circuitry.
The external command controller acts as the medium between the DSP56K target system
and a host computer. The external command controller circuit acts as a DSP56K serial
debug port driver and host computer command interpreter. The controller issues com-
mands based on the host computer inputs from a user interface program which commu-
nicates with the user.
10.11 USING THE OnCE
The following notations are used:
ACK = Wait for acknowledge on the DSO pin
CLK = Issue 24 clocks to read out data from the selected register
10.11.1 Begin Debug Activity
Most of the debug activities have the following beginning:
1. ACK
2. Save pipeline information:
a. Send command READ PDB REGISTER (10001001)
b. ACK
c. CLK
d. Send command READ PIL REGISTER (10001011)
e. ACK
f. CLK
3. Read PAB FIFO and fetch/decode info (this step is optional):
a. Send command READ PAB address for fetch (10001010)
b. ACK
c. CLK
d. Send command READ PAB address for decode (10010011)
e. ACK
