Note:
18. All status bits are cleared after any read operation is performed on STATUS.
Operation⁽¹⁸⁾
1 = data available, 0 = ADC busy
1 = event occurred, 0 = none
1 = event occurred, 0 = none
1 = event occurred, 0 = none
1 = event occurred, 0 = none
1 = fault, 0 = none
1 = event occurred, 0 = none
1 = event occurred, 0 = none
Power-up default value: 0000 0000_b = 00_h = (no events pending)
Read command byte: 0000 0010_b = 02_h
The power-up default value is 00h. Following the first conversion, however, any of the status bits may be set depending
on the measured temperature results or the existence of a diode fault.
