using the PEC data transfer.

●

Wait for ADDAT read mode: When using continuous modes, in order to avoid to

overwrite the result of the current conversion by the next one, the ADWR bit of ADCON

control register must be activated. Then, until the ADDAT register is read, the new

result is stored in a temporary buffer and the conversion is on hold.

●

Channel injection mode: When using continuous modes, a selected channel can be

converted in between without changing the current operating mode. The 10-bit data of

the conversion are stored in ADRES field of ADDAT2. The current continuous mode

remains active after the single conversion is completed.

A full calibration sequence is performed after a reset. This full calibration lasts up to 40.630

CPU clock cycles. During this time, the busy flag ADBSY is set to indicate the operation. It

compensates the capacitance mismatch, so the calibration procedure does not need any

update during normal operation.

No conversion can be performed during this time: the bit ADBSY shall be polled to verify

when the calibration is over, and the module is able to start a convertion.
