Programming Model
The READI registers do not follow the recommendations of the IEEE-ISTO 5001 - 1999, but are loosely
based on the 0.9 release of the standard. See
READI registers are classified into two categories: user-mapped register and tool-mapped registers.
User-mapped register (a memory-mapped register):
•
Ownership trace register
Tool-mapped registers (registers which can be accessed only through the development tool and are not
memory mapped):
•
Device ID register
•
Development control register
•
Mode control register 4-bit
•
User base address register
•
Read/write access register
•
Upload/download information register
•
Data trace attributes register 1
•
Data trace attributes register 2
24.6.1
Register Map
READI registers are accessible via the auxiliary port. They can be classified into two categories:
user-mapped registers and tool-mapped registers.
24.6.1.1
User-Mapped Register (OTR)
The operating system writes the ID for the current task/process in the single user-mapped register, the
READI ownership trace (OTR) register.
shows the location of the register bits. Their functions
are explained below.
The current task/process (CTP) field is updated by the operating system software to provide task/process
ID information. The OTR register can only be accessed by supervisor data attributes. Only CPU writes to
this register will be transmitted. This register is not accessible via the auxiliary port download request
message.
NOTE
This is the only READI register that is reset by HRESET.
