Please refer to IOC:IOCFGn.WU_CFG for configuring the IO's as wakeup sources.
0: Wakeup occurred from cold reset or brown out as seen in RESET_SRC
1: A wakeup has occurred from SHUTDOWN
Note: This flag will be cleared when SLEEPCTL.IO_PAD_SLEEP_DIS is asserted.
14GPIO_WU_FROM_SDR0hA wakeup from SHUTDOWN on an IO event has occurred
Please refer to IOC:IOCFGn.WU_CFG for configuring the IO's as wakeup sources.
0: The wakeup did not occur from SHUTDOWN on an IO event
1: A wakeup from SHUTDOWN occurred from an IO event
The case where WU_FROM_SD is asserted but this bitfield is not asserted will only occur in a debug session. The boot code will not proceed with wakeup from SHUTDOWN procedure until this bitfield is asserted as well.

0: Clock loss is ignored
1: Clock loss generates system reset
Note: Clock loss reset generation must be disabled when changing clock source for SCLK_LF. Failure to do so may result in a spurious system reset. Clock loss reset generation is controlled by [ANATOP_MMAP:DDI_0_OSC:CTL0.CLK_LOSS_EN]
4MCU_WARM_RESETR/W1C0hInternal. Only to be used through TI provided API.
3-1RESET_SRCR0hShows the root cause of the last system reset. More than the reported reset source can have been active during the last system reset but only the root cause is reported.
The capture feature is not rearmed until all off the possible reset sources have been released and the result has been copied to AON_PMCTL. During the copy and rearm process it is one 2MHz period in which and eventual new system reset will be reported as Power on reset regardless of the root cause.
0h = Power on reset
1h = Reset pin
2h = Brown out detect on VDDS
4h = Brown out detect on VDDR
5h = SCLK_LF, SCLK_MF or SCLK_HF clock loss detect
6h = Software reset via SYSRESET or hardware power management timeout detection.
Note: The hardware power management timeout circuit is always enabled.

7h = Software reset via PRCM warm reset request

0IO_PAD_SLEEP_DISR/W0hControls the I/O pad sleep mode. The boot code will set this bitfield automatically unless waking up from a SHUTDOWN ( RESETCTL.WU_FROM_SD is set).
0: I/O pad sleep mode is enabled, meaning all outputs and pad configurations are latched. Inputs are transparent if pad is configured as input before IO_PAD_SLEEP_DIS is set to 1
1: I/O pad sleep mode is disabled
Application software must reconfigure the state for all IO's before setting this bitfield upon waking up from a SHUTDOWN to avoid glitches on pins.
