Description
Timer Trigger Select 0 and 1
Enables the start of A/D conversion by a trigger signal.
Only set bits TRGS0 and TRGS1 while conversion is
stopped (ADST = 0).
00: A/D conversion start by software is enabled
01: A/D conversion start by TPU conversion start trigger is
10: A/D conversion start by 8-bit timer conversion start
11: A/D conversion start by external trigger pin (ADTRG) is
Reserved
These bits are always read as 1 and cannot be modified.
Clock Select 0 and 1
These bits specify the A/D conversion time. The
conversion time should be changed only when the A/D
conversion stops (ADST = 0).
The conversion time setting should exceed the conversion
time shown in section 24.5, A/D Converter Characteristics.
00: Conversion time = 530 states (max.)
01: Conversion time = 266 states (max.)
10: Conversion time = 134 states (max.)
11: Conversion time = 68 states (max.)
Reserved
These bits are always read as 1 and cannot be modified.
