8.3.2 Auto Mask (AMSK)

In the case of power up AMSK_ON and AMSK_EXS registers apply. It masks interrupts till the MON voltage crosses the UVLF threshold or sequence timeout expires whichever is sooner. In the case of power down AMSK_OFF and AMSK_ENS registers apply. It masks interrupts till the MON voltage is below the OFF threshold and then the OVLF interrupts are active.

Table 8-2 summarizes the auto-mask operation for the ACT and SLEEP transitions.

Table 8-2 Transition Table
TRANSITION AUTO-MASK APPLIED AUTO-MASK APPLIES TO AUTO-MASK INACTIVE INTERRUPTS ACTIVE FOR MON CHANNELS NOT IN AUTO-MASK
ACT (Low -> High) AMSK_ON IEN_UVLF, IEN_UVHF, IEN_OVHF SEQ_TOUT expires or rail crosses UVLF At ACT=High
ACT (High -> Low) AMSK_OFF IEN_UVLF, IEN_UVHF, IEN_OVHF Auto-mask active in transition till SEQ_TOUT expires Until SEQ_TOUT expires
SLEEP (Low -> High) ACT = High AMSK_EXS IEN_UVLF, IEN_UVHF, IEN_OVHF SEQ_TOUT expires or rail crosses UVLF Always active
SLEEP (High -> Low) ACT = High AMSK_ENS IEN_UVLF, IEN_UVHF, IEN_OVHF Auto-mask active Always active
