Note1: When converting AD in hard ware trigger by setting <HHTRGE> and <HTRGE>to “1”, set
PGFC<PG3F> to “1” (as ADTRG) in case of external TRG before enabling it. When using
an INTTBx0 of 16-bit timer, first set the <TSEL1:0> or <HTSEL1:0> bit to “00” when the
timer is not operating. Then, set the <HHTRGE> and <HTRGE> to “1” and enable trigger
operation. Finally, operate the timer so that AD conversion will be initiated at constant
intervals.
Note 2: When disabling an external trigger (
ADTRG
) for AD conversion, first clear the <HHTRGE> or
<HTRGE> bit to “0”, and clear the PGFC<PG3F> to “0”, thus configuring port G as a
general-purpose port.
Note 3: When starting AD by using external trigger (ADTRG), it can be started after enabling
(<HHTRGE> = “1” or <HTRGE> = “1”) and 3 clock at f
SYS
was executed. AD is not started
when before that time.
Note 4: When chaging compare register value of AD Monitor function, change it after setting AD
Monitor function to disable(ADMOD4<CMEN1:0>=”0”).
