Figure 6-22
Two concurrent threads are running on the system. One is running on the S12X_CPU and the other is
running on the RISC core. They both have a critical section of code that accesses the same system resource.
To guarantee that the system resource is only accessed by one thread at a time, the critical code sequence
must be embedded in a semaphore lock/release sequence as shown.
6.4.5
The XGATE module will immediately terminate program execution after detecting an error condition
caused by erratic application code. There are three error conditions:
All opcodes which are not listed in section
and opcode fetches as well as illegal load and store accesses are defined on chip level. Refer to the
S12X_MMC Section for a detailed information.
