Section 20 A/D Converter (ADC)
20.4.4
The A/D converter can be independently activated by an external trigger or an A/D conversion
request from the MTU2. To activate the A/D converter by an external trigger or the MTU2, set the
A/D trigger enable bits (TRGS[3:0]). When an external trigger or an A/D conversion request from
the MTU2 is generated with this bit setting, the ADST bit is set to 1 to start A/D conversion. The
channel combination is determined by bits CH2 to CH0 in ADCSR. The timing from setting of the
ADST bit until the start of A/D conversion is the same as when 1 is written to the ADST bit by
software.
20.4.5
The A/D converter has a built-in sample-and-hold circuit. The A/D converter samples the analog
input at the A/D conversion start delay time (t
starts conversion. Figure 20.5 shows the A/D conversion timing. Table 20.4 indicates the A/D
conversion time.
As indicated in figure 20.5, the A/D conversion time (t
time(t
conversion time therefore varies within the ranges indicated in table 20.4.
In multi mode and scan mode, the values given in table 20.4 apply to the first conversion. In the
second and subsequent conversions, time is the values given in table 20.5.
