Bit Field Type Reset Description

31-2 RESERVED R/W X

Software should not rely on the value of a reserved. Writing any

other value than the reset value may result in undefined behavior.

1 MCU_RESET_SRC R/W1C X

MCU SW reset 1: JTAG reset This bit can only be cleared by writing

a 1 to it

0 MCU_WARM_RESET R/W1C X

Indicates type of last MCU Voltage Domain reset: 0: Last MCU reset

was not a warm reset 1: Last MCU reset was a warm reset

(requested from MCU or JTAG as indicated in MCU_RESET_SRC)
