Which reset (PUC/POR/BOR) disables GIE?

6.3.3 Status Register (SR)

GIE General interrupt enable. When this bit is set, it enables maskable interrupts. When it is reset, all maskable interrupts
are disabled.

BOR. See 1.2.1

I test enable the GIE and then make watchdog timout.

The result the GIE is reset to 0 with the reset cause (SYSRSTIV) 16h = WDT time out (PUC).

Does it mean specific timing that the GIE is reset by PUC?

Hi, any update.

I would like to confirm the GIE is reset by the PUC or not (from our test result, it reset after PUC)?

Hi TinK,

This should be reset during PUC actually.

The User's Guide covers the syntax here.

Best Regards,
