Table 3-31 lists the global reset sources of the device. The global reset source signals received by the reset manager trigger the reset of all the device modules. For all hardware reset signals, the source of the reset is identified; for the software reset signals, the bit triggering the reset is identified.
Type(1) | Name | Source/Control | Description |
---|---|---|---|
H/C | SYS_PWRON_RST | porz input pin | The entire device is held in reset during porz pin assertion. porz pin is typically asserted by external PMIC at POR. PMIC keeps porz asserted until all voltage rails are ramped-up and stable. PRM extends device internal reset after porz release. Refer to Power Supply Sequences in Device Data Manual. |
H/W | SYS_WARMIN_RST | resetn input pin | Warm reset from external device. Internal warm reset is triggered by the active (falling) edge of this signal and is extended with RstTime1. |
S/C | GLOBAL_COLD_SW_RST | PRM_RSTCTRL[1] RST_GLOBAL_COLD_SW | Global software cold reset |
S/W | GLOBAL_WARM_SW_RST | PRM_RSTCTRL[0] RST_GLOBAL_WARM_SW | Global software warm reset |
H/W | TSHUT_MPU_RST | MPU voltage domain thermal sensor | Asserted when measured temperature is greater than shutdown temperature threshold |
H/W | TSHUT_IVA_RST | IVAHD voltage domain thermal sensor | |
H/W | TSHUT_CORE_RST | Device thermal sensor, placed close to the ISS, DSP, and IVA | |
H/W | TSHUT_DSPEVE_RST | DSPEVE voltage domain thermal sensor | |
H/W | TSHUT_GPU_RST | GPU voltage domain thermal sensor | |
H/W | ICEPICK_RST | ICEPick™ module | ICEPick warm reset. It is used only in emulation mode. |
H/C | ICEPICK_POR_RST | ICEPick module | ICEPick cold reset. It is used only in emulation mode. |
H/W | MPU_WDT_RST | WD_TIMER2 or MPU subsystem WDT | It is triggered by a time-out event. |
