ADC: GOVRE Bit is not Set when Disabling a Channel
ADC: OVRE Flag Behavior
ADC: EOC Set although Channel Disabled
ADC: Spurious Clear of EOC Flag
ADC: Sleep Mode
GOVRE should be set but is not.
None
When disabling channel “y” at the same instant as an end of conversion on channel “x”, EOC[x]
and DRDY being already active, GOVRE does not rise.
Note:
None
When the OVRE flag (on channel i) has been set but the related EOC status (of channel i) has
been cleared (by a read of CDRi or LCDR), reading the Status register at the same instant as an
end of conversion (causing the set of EOC status on channel i), does not lead to a reset of the
OVRE flag (on channel i) as expected.
None
If a channel is disabled while a conversion is running and if a read of CDR is performed at the
same time as an end of conversion of any channel occurs, the EOC of the channel with the con-
version running may rise (whereas it has been disabled).
Do not take into account the EOC of a disabled channel
If “x” and “y” are two successively converted channels and “z” is yet another enabled channel
(“z” being neither “x” nor “y”), reading CDR on channel “z” at the same instant as an end of con-
version on channel “y” automatically clears EOC[x] instead of EOC[z].
None.
If Sleep mode is activated while there is no activity (no conversion is being performed), it will
take effect only after a conversion occurs.
To activate sleep mode as soon as possible, it is recommended to write successively, ADC
Mode Register (SLEEP) then ADC Control Register (START bit field); to start an analog-to-digi-
tal conversion, in order put ADC into sleep mode at the end of this conversion.
• EOC[x] already active,
• DRDY already active,
• GOVRE inactive,
• previous data stored in LCDR being neither data from channel “y”, nor data from channel “x”.
