Trigger Select

Selects the external trigger (

ADTRG) or an A/D conversion

start trigger from the MTU2 or MTU2S as an A/D

conversion start trigger.

When the external trigger is selected (EXTRG

= 1), upon

input of a low-level pulse to the

ADTRG pin after the

TRGE bit is set to 1, the A/D converter detects the falling

edge of the pulse, and sets the ADST bit in ADCR to 1.

The operation which is performed when 1 is written to the

ADST bit by software is subsequently performed. A/D

conversion start by the external trigger input is enabled

only when the ADST bit is cleared to 0.

When the external trigger is used as an A/D conversion

start trigger, the low-level pulse input to the ADTRG pin

must be at least 1.5 A

φ clock cycles in width.

0: A/D converter is started by the A/D conversion start

trigger from the MTU2 or MTU2S

1: A/D converter is started by the external pin (

ADTRG)
