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
10: A/D conversion start by 8-bit timer conversion start
11: A/D conversion start by external trigger pin (ADTRG)
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 ADST = 0.
Specify a setting that gives a value within the range
shown in table 26.9 or 26.22 in section 26, Electrical
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.
