Mode
Setting ADMOD0<REPEAT> and ADMOD0<SCAN> to 11 selects channel scan
repeat conversion mode.
In this mode, data on the specified scan channels is converted repeatedly. When
each scan conversion has been completed, ADMOD0<EOCF> is set to 1 and an
INTAD interrupt request is generated. ADMOD0<ADBF> is not cleared to 0 but
held 1.
To stop conversion in a repeat conversion mode (e.g., in cases (C) and (d)), write 0 to
ADMOD0<REPEAT>. After the current conversion has been completed, the repeat
conversion mode terminates and ADMOD0<ADBF> is cleared to 0.
Switching to a halt state (IDLE2 mode with ADMOD1<I2AD> cleared to 0, IDLE1
mode or STOP mode) immediately stops operation of the AD converter even when
AD conversion is still in progress. In repeat conversion modes (e.g., in cases (C) and
(d)), when the halt is released, conversion restarts from the beginning. In single
conversion modes (e.g., in cases (a) and (b)), conversion does not restart when the
halt is released (the converter remains stopped).
Table 3.11.2 shows the relationship between the AD conversion modes and
interrupt requests.
