8.4.3.3.3 SLEEP Transition 0→1
GUID-20210303-CA0I-NDRS-5ZLZ-5WFHGLVRRW7L-low.svgFigure 8-10 SLEEP 0→1 Transition

  1. The TPS389006 takes several actions on the SLEEP 0→1 transition:
    1. The synchronization counter is reset to 0.
    2. The REC_ACTIVE bit is set, and SEQ[1:0] bits are updated to 10b.

    3. If the sequence overwrite bit is enabled (EN_SEQ_OW=1), the sequence logging registers (SEQ_EXS_LOG[N]) are overwritten with new data. If there was data in the registers that was not read by the host (SEQ_EXS_RDY still set), the sequence overwrite flag (SEQ_EXS_OW) is set.

    4. If the timestamp overwrite bit is enabled (EN_TS_OW=1), the timestamp logging registers (SEQ_TIME_xSB[N]) are overwritten with new data. If there was data in the registers that was not read by the host (TS_RDY still set), the timestamp overwrite flag (TS_OW) is set.

    5. If the sequence overwrite bit is disabled (EN_SEQ_OW=0) and there was data in the registers SEQ_EXS_LOG[N] that was not read and acknowledged by the host (SEQ_EXS_RDY still set), the sequence overwrite flag (SEQ_EXS_OW) is set, and the registers are not overwritten with new data.

    6. If the timestamp overwrite bit is disabled (EN_TS_OW=0) and there was data in the registers SEQ_TIME_xSB[N] that was not read and acknowledged by the host (TS_RDY still set), the timestamp overwrite flag (TS_OW) is set, and the registers are not overwritten with new data.

    7. The internal sequence timer is (re)started.
  2. Relevant TPS389006 inputs selected with auto-mask register AMSK_EXS are set with masked (disabled) interrupts for UVLF, UVHF, and OVHF conditions.
  3. As each rail passes the UVLF threshold (UV_LF[N]), automatically (and expected to happen within about 5-10 µs) the relevant UV and OV interrupts are unmasked and enabled/disabled according to the IEN_UVLF, IEN_UVHF, and IEN_OVHF registers.
  4. As each rail passes the UVLF or OFF threshold (depending on SEQ_UP_THLD.OFF_UV[N] register setting), the rail is tagged with a counter corresponding to the order of rising edge transition. A timestamp is also logged.
    1. The tag value is stored in the relevant status register SEQ_EXS_LOG[N] if allowed as per overwrite settings and status. Also, the timestamp of the event is stored in registers SEQ_TIME_MSB[N] and SEQ_TIME_LSB[N] as allowed by the overwrite settings and status.
    2. The SEQ_EXS_LOG[N] register is compared to the expected sequence order value defined in register SEQ_EXS_EXP[N], and an interrupt is generated if different and if relevant interrupt enable bit is set (IEN_SEQ_EXS). Note that if overwrite settings and recording status do not allow writing new data to the logging registers, then the comparison cannot be performed and no interrupt will be generated.
  5. After a timeout, tagging stops.
    1. The REC_ACTIVE bit is cleared.
    2. If rails are up with the correct sequence, TPS389006 is in ACTIVE state and starts normal monitoring.
    3. If any rail has a tag not matching the configured value in SEQ_EXS_EXP[N] register, NIRQ is asserted. TPS389006 continues normal monitoring.
