3.12.1 Operation
(1)
Analog Reference Voltage
High analog reference voltage is applied to the VREF
pin, and low analog reference voltage is applied to
AGND pin.
The reference voltage between VREG and AGND is
divided by 1024 using ladder resistance, and com-
pared with the analog input voltage for A/D conversion.
(2)
Analog Input Channels
Analog input channel is selected by ADMOD <ADCH1,
0>. However, which channel to select depends on the
operation mode of the A/D converter.
In fixed analog input mode, one channel is selected by
ADMOD <ADCH1, 0> among four pins: AN0 to AN3.
In analog input channel scan mode, the number of
channels to be scanned from AN0 is specified by
ADMOD <ADCH1, 0>, such as AN0
AN1
→
AN2, and AN0
→
AN1
When reset, A/D conversion channel register will be ini-
tialized to ADMOD <ADCH1, 0> = 00, so that AN0 pin
will be selected.
The pins which are not used as analog input channel
can be used as ordinary input port P5.

Starting A/D Conversion
A/D conversion starts when A/D conversion register
ADMOD <ADS> is written “1". When A/D conversion
starts, A/D conversion busy flag ADMOD <ADBF>
which indicates “A/D conversion is in progress” will be
set to “1".
(4)
A/D Conversion Mode
Both fixed A/D conversion channel mode and A/D
conversion channel scan mode have two conversion
modes, i.e., single and repeat conversion modes.
In fixed channel repeat mode, conversion of specified
one channel is executed repeatedly.
In scan repeat mode, scanning from AN0,
executed repeatedly.
A/D conversion mode is selected by ADMOD <REPET,
SCAN>.

A/D Conversion Speed Selection
There are two A/D conversion speed modes: high
speed mode and low speed mode. The selection is
executed by ADMOD <ADCS> register.
When reset, ADMOD <ADCS> will be initialized to “0,”
so that high speed conversion mode will be selected.
(6)
A/D Conversion End and Interrupt
A/D conversion single mode
ADMOD <EOCF> for A/D conversion end will be
set to “1,” ADMOD <ADBF> flag will be reset to “0,”
and INTAD interrupt will be enabled when A/D conver-
sion of specified channel ends in fixed conversion
channel mode or when A/D conversion of the last
channel ends in channel scan mode.
A/D conversion repeat mode
For both fixed conversion channel mode and con-
version channel scan mode, INTAD should be disabled
when in repeat mode. Always set the INTE0AD at
“000,” that disables the interrupt request.
Write “0” to ADMOD <REPET> to end the repeat
mode. Then, the repeat mode will be exited as soon as
the conversion in progress is completed.
(7)
Storing the A/D Conversion Result
The results of A/D conversion are stored in ADREG0 to
ADREG3 registers for each channel. In repeat mode,
the registers are updated whenever conversion ends.
ADREG0 to ADREG3 are read-only registers.
(8)
Reading the A/D Conversion Result
The results of A/D conversion are stored in ADREG0 to
ADREG3 registers. When the contents of one of
ADREG0 to ADREG3 registers are read, ADMOD
<EOCF> will be cleared to “0".
Setting example:
When the analog input voltage of the
AN3 pin is A/D converted and the
result is stored in the memory
address FF10H by A/D interrupt
INTAD routine.
