When the status pin is programmed as EOC and the polarity is set as active low, the pin works in the following
manner: The EOC output goes LOW immediately following CONVST going LOW when manual trigger is
programmed. EOC stays LOW throughout the conversion process and returns to HIGH when the conversion has
ended. The EOC output goes low for 3 conversion clocks (CCLK) after the previous rising edge of EOC, if auto
trigger is programmed.
This status pin is programmable. It can be used as an EOC output (CFR_D[7:6] = 1, 1) where the low time is
equal to the conversion time. This status pin can be used as INT. (CFR_D[7:6] = 1, 0) which is set LOW at the
end of a conversion is brought to HIGH (cleared) by the next read cycle. The polarity of this pin, used as either
function (EOC or INT), is programmable through CFR_D7.
The ADS8329/30 has a comprehensive built-in power-down feature. There are three power-down modes: Deep
power-down mode, Nap power-down mode, and auto nap power-down mode. All three power-down modes are
enabled by setting the related CFR bits. The first two power-down modes are activated when enabled. A wakeup
command, 1011b, can resume device operation from a power-down mode. Auto nap power-down mode works
slightly different. When the converter is enabled in auto nap power-down mode, an end of conversion instance
(EOC) puts the device into auto nap powerdown. The beginning of sampling resumes operation of the converter.
The contents of the configuration register is not affected by any of the power-down modes. Any ongoing
conversion when nap or deep powerdown is activated is aborted.
