Description
Timer Trigger Select 1 and 0
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
10: A/D conversion start by 8-bit timer conversion
11: A/D conversion start by external trigger pin
Reserved
These bits are always read as 1 and cannot be
modified.
Clock Select 1 and 0
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 27.10 (H8S/2258 Group),
table 27.23 (H8S/2239 Group), table 27.35
(H8S/2238B and H8S/ 2236B), table 27.47
(H8S/2238R and H8S/ 2236R), or table 27.57
(H8S/2237 Group and H8S/2227 Group).
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.
