The PL and PS SYSMON units operate independently. The operating modes include single read, default sequence, and auto sequence. The SYSMON units normally operate in their default sequence mode. They can be configured for a custom sequence while in this mode. Once the custom configuration is complete, set the sequence mode in the CONFIG_REG register. The activity of the PS ADC can be monitored by reading the AMS.MON_STATUS register fields [mon_data], [channel], and [busy].
