CHAPTER 17 8/10-BIT A/D CONVERTER
[bit13] INTE: interrupt enable
This bit is used to enable or disable interrupts at conversion end.
•
0: Interrupts prohibited
•
1: Interrupts allowed
Set this bit when using
μ
DMAC. An interrupt request will then trigger
μ
DMAC start.
This bit is initialized to "0" at reset.
Also read the Caution when using the conversion data protection function in Section "17.6
Conversion Data Protection Function of 8/10-Bit A/D Converter".
[bit12] PAUS: A/D converter pause
This bit is set when A/D conversion pauses.
There is only one register for storing the results of A/D conversion. When conversion is
performed continuously, data stored previously is overwritten unless conversion results is
transferred by
μ
DMAC. To prevent overwriting data, the next conversion result cannot be
stored before the contents of the data register has been transferred by
μ
DMAC, and A/D
conversion will be stopped in between. The A/D converter resumes conversion as soon as
data transfer by
μ
DMAC ends.
This register is effective only when
μ
DMAC is used.
Also read the Caution when using the conversion data protection function in Section "17.6
Conversion Data Protection Function of 8/10-Bit A/D Converter".
This bit is initialized to "0" at reset.
[bit11, bit10] STS1, STS0: start source select
These bits select A/D start sources.
In a mode for which two start sources apply, the first of the sources to occur will trigger start.
Start sources become effective from the time they are rewritten. Exercise caution when
rewriting during A/D operation.
•
When an external pin trigger is selected, a falling edge is detected.
•
When the external trigger input level is "L", A/D conversion will start as soon as this bit is
rewritten to select the external trigger start.
•
The output of PPG1 is selected at the time the timer is selected.
These bits are initialized to "00
B
" at reset.
