N/A
measurement data from the last channel in the auto sequence is
written to the status registers. This bit is cleared when a read operation
is performed on status register.
End of Conversion signal: This signal transitions to an active High at

N/A
the end of an ADC conversion when the measurement is written to the
status register of the SYSMON hard macro. This bit is cleared when a
read operation is performed on the status register.

Channel selection outputs: The ADC input MUX channel selection for
N/A the current ADC conversion is placed on these outputs at the end of an
ADC conversion.
Alarm Output Status Register (AOSR)
The Alarm Output Status Register (AOSR) contains the alarm outputs for the AXI Sysmon ADC core. This register
is read only. Any attempt to write the bits of the register will not change the bits. The Alarm Output Status Register
bit definitions are shown in Figure 5 and explained in Table 7.
