code in the internal ROM. Patch program code must be read into the internal RAM from
external memory during the startup routine.
significant code correction can be performed by replacing program code with single-byte
instruction code which generates a software interrupt (SWI) to make a branch to a specified
location in the internal RAM area.
the program code in the internal I/O, internal RAM and external ROM areas.
following sections, any references to bank0 also apply to other banks.
The TMP91CW40 has a program patch logic, which enables the user to fix the program
Up to six 2-byte sequences (12 bytes in total) can be replaced with patch code. More
The program patch logic only compares addresses in the internal ROM area; it cannot fix
Each of six banks is independently programmable, and functionally equivalent. In the
