Chapter 23 Successive Approximation Type A/D Converter
FEUL62Q1000
23-24
Figure 23-3 shows a setting example when one-time A/D conversion is performed in HALT mode using channel 1 and 0.
Figure 23-3 Example of A/D Conversion Setting (Converting in HALT mode)
Set the mode of the reference voltage.
Set the A/D conversion mode. (SALP = 1)
Set the channel to be A/D-converted. (SADEN0=0x03)
Set the ENOSC bit of the FCON register to "1" to start supplying
the high-speed clock.
The high-speed clock is supplied after the oscillation stabilization
time has passed.
Set the start and end of A/D conversion.
When SARUN bit="1", the A/D conversion is started.
Setting
start
Set the general-purpose port of AINn to the both input and output are
disable.
To use the voltage that is input from the V
REF
pin as the reference
voltage, set the mode of that disables the input and disables the output.
End
If enabling
SADINT
(SA-ADC interrupt), set the ESAD bit of the IE23
register to "1".
Execute the EI instruction to set the master interrupt enable flag (MIE) to "1".
Interrupt generated?
YES
NO
A/D conversion is
completed
Read the A/D conversion result.
(n=0, 1)
The SARUN bit is automatically cleared to "0".
Set IE register
Execute EI instruction
Set PnMOD0 to 7 registers
Set VREFCON register
Set SADMOD register
Set SADEN0 register
Set SADCON register
Read SADRn register
Starts A/D conversion
Set FCON register
Set SADLMOD register
Set SADUPL register
Set SADLOL register
To use the upper/lower limit function for the conversion result, this
setting is required.
Set HALT mode
Entering the HALT mode
Set ESAD bit of IE23 register to "0".
Set HLT bit(or HLTH bit) of SBYCONL register to "1".
Release the HALT mode
