17.4.2 Starting AD Conversion
Note 1: Delay time from trigger to start of AD conversion.
Note 2: Delay time to the 2nd or after conversion in plural conversions with one trigger.

the ongoing program and start AD conversion correspond to PMD trigger number.
is handled after the ongoing program is completed.
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.
If the PMD trigger occurs while an AD conversion is in progress, the PMD trigger is handled stop
If a higher-priority trigger occurs while an AD conversion is in progress, the higher-priority trigger

・PMD trigger (See “17.3.5 PMD Trigger Program Setting Registers.”)
AD conversion is started by software or one of the following three trigger signals.
・ Timer trigger (TMRB5) (See “17.3.6 Timer Trigger Program Setting Registers.”)
・Software trigger (See “17.3.7 Software Trigger Program Registers.”）
These start triggers are given priorities as shown below.
