Chapter 25, Analog-to-Digital
Converter (ADC), p. 600
In Section 25.3.4.2, CTU in trigger mode, replace the sentence:
If another CTU conversion is triggered before the end of the conversion, that request is
discarded.
with:
If another CTU conversion is triggered before the end of the conversion, that request is
discarded. However, if the CTU has triggered a conversion that is still ongoing on a channel,
it will buffer a second request for the channel and wait for the end of the first conversion before
requesting another conversion. Thus, two conversion requests close together will both be
serviced.

Converter (ADC), page 603
Add Note to Section 25.3.10, Auto-clock-off mode:
Note: The auto-clock-off feature cannot operate when the digital interface runs at the same
rate as the analog interface. This means that when MCR.ADCCLKSEL = 1, the analog clock
will not shut down in IDLE mode.
Chapter 25, Analog-to-Digital
Converter (ADC), page 610
In Section 25.4.6.2, Main Status Register (MSR), replace the ADCSTATUS field description with
the following:
The value of this parameter depends on ADC status:
000 IDLE — The ADC is powered up but idle.
001 Power-down — The ADC is powered down.
010 Wait state — The ADC is waiting for an external multiplexer. This occurs only when the
DSDR register is nonzero.
011 Reserved
100 Sample — The ADC is sampling the analog signal.
101 Reserved
110 Conversion — The ADC is converting the sampled signal.
111 Reserved
Chapter 26, Cross Triggering
Unit (CTU), page 633
At the end of Section 26.4.1, Event Configuration Registers (CTU_EVTCFGRx) (x = 0...63), add
the following Note:
NOTE
The CTU tracks issued conversion requests to the ADC. When the ADC
is being triggered by the CTU and there is a need to shut down the ADC,
the ADC must be allowed to complete conversions before being shut
down. This ensures that the CTU is notified of completion; if the ADC
is shut down while performing a CTU-triggered conversion, the CTU is
not notified and will not be able to trigger further conversions until the
device is reset.
