DS32 PS_DONE Green MPSoC U1 bit file download is complete
DS33 PS_ERR_STATUS
(1)
Green
PS error status indicates a secure lockdown state.
Alternatively, it can be used by the PMU firmware
to indicate system status.
DS35 PS_ERR_OUT
(1)
Red
PS error out is asserted for accidental loss of power,
an error in the PMU that holds the CSU in reset, or
an exception in the PMU.
DS36 POR_RST_B Red
POR U22 asserts RST_B low when any of the
monitored voltages (IN_) falls below its respective
threshold, any EN_ goes low, or MR is asserted.
DS49 UTIL_1V13_PG Green UTIL_1V13 1.13 VDC power on
DS51 USB3 MIC2544 U121 FLG Green PS USB 3.0 ULPI VBUS power error
DS53 UTIL_5V0_PGOOD Green UTIL_5V0 5 VDC power on
