16.5 Operation Descriptions
16.5.1 Analog Reference Voltages
For the High-level and Low-level analog reference voltages, the AVDD5and AVSSpins are used . If AD-
MOD3<RCUT> is set to "1", current flowing between AVDD5 and AVSS can be controlled to reduce
consumption current. When AD converter is used, ADMOD3<RCUT> is set to "0".
Note 1: During AD conversion, do not change the output data of port H/I/J, to avoid the influence on the conver-
sion result.
Note 2: AD conversion results might be unstable by the following conditions.
Input operation is executed.
Output operation is executed.
Output current of port varies.
Take a countermeasure such as averaging the multiple conversion results, to get precise value.
16.5.2 Starting AD Conversion
AD conversion is started by software or
timer
trigger signals.
These start triggers are given priorities as shown below.
If the upper level trigger occurs while an AD conversion is in progress, the upper level trigger is handled
stop the ongoing program and start AD conversion correspond to upper level trigger.
It has some delay from generation of trigger to start of AD conversion. The delay depends on the trigger.
The following timing chart and table show the delay.
