Table 14. Readback and FIFO Contents with Aperture Mode Enabled
The second waveform shows an interrupt operation
assuming that aperture mode is disabled (or that
ΔX =
ΔY = 0 LSB), assuming that the AP service interrupts at
a frequency faster than the selected TSC sample rate.
Every sample induces a FIFO event and an interrupt
pulse as shown. The interrupt waveform is significantly
busier than that shown in the first waveform. Duration
information can now be directly determined from the
FIFO samples since each sample is logged and occurs
at the programmed sample rate. Table 15 lists the read-
back data assuming the FIFO does not fill up.
The third waveform in Figure 16 shows an interrupt oper-
ation assuming that the MAX11800/MAX11801 are infre-
quently serviced. Ensure that the FIFO does not overflow.
No duration information is available at resolutions below
the servicing rate. Either the set of data shown in Table
14 or the set shown in Table 15 appears in the FIFO
when read, depending on the aperture setting.
