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.
register. The data can be transferred to the RAM by interrupt software management or
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.
