Note When the hardware trigger mode is selected, select a trigger mode by using the ADAnM2.ADAnTMD1
Cautions 1. In the software trigger mode, conversion is triggered when 1 is written to the ADAnCE bit.
and ADAnM2.ADAnTMD0 bits.
2. If the ADAnM0, ADAnM2, and ADAnS registers are written during A/D conversion
ADAnM0
(n = 0, 1)
In the hardware trigger mode (external trigger mode or timer trigger mode 0, 1), the trigger
signal stands by when 1 is written to the ADAnCE bit.
The ADAnCE bit is not cleared to 0 even after the A/Dn conversion end interrupt request
signal (INTADn) is generated in all modes.
therefore, write 0 to the ADAnCE bit.
(ADAnEF bit = 1), the operation is performed as follows in each mode.
• In software trigger mode
• In hardware trigger mode
After reset: 00H
A/D conversion is stopped and executed again from the beginning.
A/D conversion is stopped and the trigger standby state is restored again.
