RTP Control Registers

Table 36-15. RTP RAM 3 Trace Region Registers (RTPRAM3REGn) Field Descriptions (continued)

Bit Field Value Description

27-24 BLOCKSIZE These bits define the length of the trace region. Depending on the setting of INV_RGN

(RTPGLBCTRL), accesses inside or outside the region defined by the start address and

blocksize will be traced. If all bits of BLOCKSIZE are 0, the region is disabled and no data will

be captured.

Region size (in bytes):

0 0

1h 256

2h 512

3h 1K

4h 2K

Ah 128K

Bh 256K

Ch-Fh Reserved

23-18 Reserved 0 Read returns 0. Writes have no effect.

17-0 STARTADDR 0-3 FFFFh These bits define the starting address of the address region that should be traced. The start

address has to be a multiple of the block size chosen. If the start address is not a multiple of

the block size, the start of the region will begin at the next lower block size boundary.
