PRODUCTION DATA
In the case of power up, AMSK_ON register applies. AMSK_ON masks interrupts until the MON voltage crosses the UVLF threshold or sequence timeout expires whichever is sooner. In the case of power down AMSK_OFF register applies. AMSK_ON masks interrupts until the MON voltage is below the OFF threshold and then the OVLF interrupts are active.
Table 7-2 summarizes the auto-mask operation for power up and power down.
