RX13T Group
 With group priority control operation mode enabled (ADCSR.ADCS[1:0] bits = 01b and ADGSPCR.PGS bit = 1),
the ADGSPCR.GBRSCN bit is set to 1 and the scanning of the low-priority group started by a trigger is stopped.
Note: When group priority control operation mode has been enabled (ADCSR.ADCS[1:0] bits = 01b and
ADGSPCR.PGS bit = 1), do not set the ADST bit to 1.
Note: When group priority control operation mode has been enabled (ADCSR.ADCS[1:0] bits = 01b and
ADGSPCR.PGS bit = 1) and ADGSPCR.GBRP = 1, do not set the ADST bit to 0. When forcibly terminating A/D
conversion, follow the procedure for clearing the ADST bit.
Note: When the single-scan continuous function is used (ADGSPCR.GBRP bit = 1) with group priority control operation
mode enabled (ADCSR.ADCS[1:0] bits = 01b and ADGSPCR.PGS bit = 1), the ADST bit remains as 1.
