10.4
The core of the XGATE module is a RISC processor which is able to access the MCU’s internal memories
and peripherals (see
by an XGATE request. Then it executes a code sequence (thread) that is associated with the requested
XGATE channel. Each thread can run on a priority level ranging from 1 to 7. Refer to the S12X_INT
