is tested, but not characterized. Analog modules: ADC, Op amp/Comparator, and Comparator voltage
reference, will have degraded performance. Refer to parameter
maximum BOR values.
Because the sample caps will eventually lose charge, clock rates below 10 kHz may affect linearity
performance, especially at elevated temperatures.
The parameter t
module is turned on (AD1CON1<ADON> = 1). During this time, the ADC result is indeterminate.

These parameters are characterized, but not tested in manufacturing.
These parameters are characterized, but not tested in manufacturing.
Because DMA transfers use the CPU data bus, this time is dependent on other functions on the bus.
