XGATE Single Step — This bit forces the execution of a single instruction if the XGATE is in DEBUG Mode and
no software error has occurred (XGSWEIF cleared).
Read:
0 No single step in progress
1 Single step in progress
Write
0 No effect
1 Execute a single RISC instruction
Note: Invoking a Single Step will cause the XGATE to temporarily leave Debug Mode until the instruction has
Fake XGATE Activity — This bit forces the XGATE to flag activity to the MCU even when it is idle. When it is set
the MCU will never enter system stop mode which assures that peripheral modules will be clocked during XGATE
idle periods
Read:
0 XGATE will only flag activity if it is not idle or in debug mode.
1 XGATE will always signal activity to the MCU.
Write:
0 Only flag activity if not idle or in debug mode.
1 Always signal XGATE activity.
XGATE Software Error Interrupt Flag — This bit signals a pending Software Error Interrupt. It is set if the RISC
core detects an error condition (see
this bit is set. Clearing this bit will terminate the current thread and cause the XGATE to become idle.
Read:
0 Software Error Interrupt is not pending
1 Software Error Interrupt is pending if XGIE is set
Write:
0 No effect
1 Clears the XGSWEIF bit
XGATE Interrupt Enable — This bit acts as a global interrupt enable for the XGATE module
Read:
0 All XGATE interrupts disabled
1 All XGATE interrupts enabled
Write:
0 Disable all XGATE interrupts
1 Enable all XGATE interrupts
