(2) Operation of multiple channel conversion
Remark
(1) AD0CE bit = 1 (enable)
(2) Signal of ANI01 pin is A/D-converted
(3) Conversion result is stored in AD0CR1 register
(4) Signal of ANI03 pin is A/D-converted
(5) Conversion result is stored in AD0CR3 register
Figure 12-15. Example of Multiple Channel Conversion Operation (A/D Trigger Mode): A/D Converter 0
Note Two or more can be specified by the ADnCHEN register.
Remark
The signals of two or more analog input pins specified by the ADnCHEN register are converted sequentially
starting from the pin with the lowest number. The result of conversion is stored in the ADnCRk register
corresponding to the analog input pin.
When conversion of the signals of all the specified analog input pins is completed, an A/Dn conversion end
interrupt request signal (INTADn) is generated. After A/D conversion is completed, the A/D converter stops
conversion operation with the ADnSCM.ADnCE bit remaining set to 1. The A/D conversion can be restarted
by setting the ADnCE bit to 1.
This operation is suitable for an application where two or more analog input signals should be monitored.

AD0SCM
This is an operation example when the AD0SCM.AD0PLM, AD0TRG1, and AD0TRG0 bits = 000,
AD0CTL0.AD0MD1 and AD0CTL0.AD0MD0 bits = 00, and AD0CHEN register = 002AH.
Note
Note
However, A/D conversion is sequentially executed starting from the pin with the lowest number.
A/D converter 0: n = 0, k = 0 to 5
A/D converter 1: n = 1, k = 0 to 7
