Bit 7—A/D Start Flag (ADSF): Bit 7 controls and indicates the start and end of A/D conversion.
Bit 7: ADSF
0
1
Bits 6 to 0—Reserved Bits: Bits 6 to 0 are reserved; they are always read as 1, and cannot be
modified.
12.3
12.3.1
The A/D converter operates by successive approximations, and yields its conversion result as 8-bit
data.
A/D conversion begins when software sets the A/D start flag (bit ADSF) to 1. Bit ADSF keeps a
value of 1 during A/D conversion, and is cleared to 0 automatically when conversion is complete.
The completion of conversion also sets bit IRRAD in interrupt request register 2 (IRR2) to 1. An
A/D conversion end interrupt is requested if bit IENAD in interrupt enable register 2 (IENR2) is
set to 1.
If the conversion time or input channel needs to be changed in the A/D mode register (AMR)
during A/D conversion, bit ADSF should first be cleared to 0, stopping the conversion operation,
in order to avoid malfunction.
12.3.2
The A/D converter can be made to start A/D conversion by input of an external trigger signal.
External trigger input is enabled at pin ADTRG when bit IRQ4 in port mode register 2 (PMR2) is
set to 1, and bit TRGE in AMR is set to 1. Then when the input signal edge designated in bit IEG4
of the IRQ edge select register (IEGR) is detected at pin ADTRG, bit ADSF in ADSR will be set
to 1, starting A/D conversion.
Figure 12.2 shows the timing.
