12.5.2 Continuous scan mode operations
ANIn0 pin, and A/D conversion is executed continuously. The A/D conversion results are stored in the ADAnCRm
register corresponding to the analog input pin.
(INTADn) is generated. After the end of A/D conversion, the conversion is started again from the ANIn0 pin, unless
the ADAnM0.ADAnCE bit is cleared to 0. It is not necessary to set (1) the ADAnM0.ADAnCE bit to restart A/D
conversion

In this mode, the analog input pins (ANInm)
When conversion of all the specified analog input pins ends, the A/Dn conversion end interrupt request signal
In the continuous scan mode, only the 1-buffer mode is supported.
Notes 1. Only the ANI00 and ANI01 pins can be used when A/D converter 0 of the V850E/IA3 is used.
This mode is suitable for applications in which multiple analog inputs are constantly monitored.
Remark
Remark
(1) The ADA0CE bit = 1 (enable)
(2) The ANI00 pin is A/D converted
(3) The conversion result is stored in the ADA0CR0 register (8) The INTAD0 interrupt request signal is generated
(4) The ANI01 pin is A/D converted
(5) The conversion result is stored in the ADA0CR1 register (10) To end the conversion, the ADA0CE bit = 0 (stop)
Note Set by the ADAnS.ADAnS0 to ADAnS.ADAnS2 bits.
