OCD Interrupts
rently executing mode, only PID and DCCPU can be written. Illegal access to the registers will
be ignored with no error reporting.
Table 9-3.
To support custom debug protocols running in software the OCD system support giving inter-
rupts to the CPU when DCEMU is written or when DCCPU is read. A software protocol handler
can then be triggered by these interrupts instead of having to poll DCSR to see if the data in
DCCPU or DCEMU has been read or written.
To enable these interrupts the user must do the following:
Register
Development Control (DC)
Watchpoint Trigger (WT)
Data Trace Control (DTC)
Data Trace Start Address (DTSA) Channel 1 to
2
Data Trace End Address (DTEA) Channel 1 to
2
PC Breakpoint/Watchpoint Control (BWC)
Data Breakpoint/Watchpoint Control (BWC)
PC Breakpoint/Watchpoint Address (BWA)
Data Breakpoint/Watchpoint Address (BWA)
Breakpoint/Watchpoint Data (BWD)
Ownership Trace Process ID (PID)
Debug Instruction Register
Debug Program Counter
Debug Communication CPU (DCCPU)
Debug Communication Emulator (DCEMU)
• Program the interrupt controller with the correct priority and handler address for the interrupt.
• Enable the interrupts from the OCD by setting the corresponding bits in DCCR
