Section 23 A/D Converter
Note 1.
ADCAnDBiCR[15:00] is
•
retained until the next A/D conversion result is overwritten when
ADCAnCTL1.ADCAnRCL bit = 0,
•
cleared after reading ADCAnDBiCR register when
ADCAnCTL1.ADCAnRCL bit = 1.
Note 2.
The result of the diagnostic A/D conversion of an internal reference voltage is
stored in ADCAnDGCR, not in ADCAnLCR, ADCAnCmCR (refer to Section
23.4.5 (5), ADCAnDGCR – A/D Converter Diagnosis Conversion Result
Register).
21
ADCAn
DBiUR
Indicates the update status of the A/D conversion result:
0: The A/D conversion result has been read from ADCAnDBiCR (the result has
not been updated)
1: The A/D conversion result has not been read from ADCAnDBiCR (the result
has been updated)
This bit is cleared after the conversion result is read.
20 to 16
ADCAn
DBiCN[4:0]
Indicates the number of the channel to which the conversion result in
ADCAnDBiCR [15:00] belongs:
00001 × m = CHm
15 to 0
ADCAn
DBiCR
[15:00]
Indicates the result of the A/D conversion.
The resolution and alignment depend on ADCAnCTL1.ADCAnCTYP and
ADCAnCTL1.ADCAnCRAC as follows:
