ANAx Scan Request
Analog Channel 0, 1, 3–7 Scan Requested Bits
Set by the application; cleared by the PIR engine.
These bits allow the user application to request the Engine to perform an A/D conversion on the
unreserved analog inputs. When requested, the Engine will reconfigure the appropriate I/O pin to a single-
ended, unbuffered input using a 2-volt reference. It will then take the next sample and store it in the PIR
ADC Result Value Registers and clear all ANAx Scan Request bits. The I/O configuration for the ANAx
pin is not returned to its previous configuration by the Engine. If required, the user application must
perform this task.
If multiple request bits are set simultaneously, the Engine will only scan the lowest numbered ADC
channel requested and ignore any other requests. The user application should set one request bit then
poll it to determine when the conversion is complete and the data is ready.
When ADC Scan requests are being serviced by the PIR engine, ADC conversions on the PIR sensor are
suspended. Therefore the user application should be careful not to continuously request ADC Scans. The
Process Rate Register in the Advanced PIR Engine section can be monitored to ensure the Engine is
receiving enough time to perform its required PIR Sensor ADC scans.
0 = No conversion requested/last conversion completed.
1 = Perform a conversion on this channel.
