Write Sequencer Interrupt
0 = Interrupt not set
1 = Interrupt is set
The Write Sequencer asserts this flag
when it has completed a programmed
sequence - ie it indicates that the
Write Sequencer is NOT Busy. It is
cleared when a ‘1’ is written.
Thermal Shutdown Interrupt
0 = Interrupt not set
1 = Interrupt is set
This flag is asserted a thermal
shutdown condition has been
detected. It is cleared when a ‘1’ is
written.
Write Sequencer interrupt mask
0 = do not mask interrupt
1 = mask interrupt
Thermal Shutdown interrupt mask
0 = do not mask interrupt
1 = mask interrupt
Thermal Shutdown interrupt polarity
0 = active low (interrupt is triggered
when temperature threshold is
exceeded)
1 = active high (interrupt is triggered
when temperature is normal)
Interrupt output polarity
0 = Active low
1 = Active high
IRQ Output pin configuration
0 = CMOS
1 = Open Drain
