R/W Description
R/W A/D Interrupt Enable
Enables or disables the generation of A/D conversion end
interrupts (ADI) to the CPU. Operating modes must be
changed when the ADST bit is 0 to prevent incorrect
operations.
When A/D conversion ends and the ADF bit in ADSR is
set to 1 and this bit is set to 1, ADI is sent to the CPU. By
clearing the ADF bit or the ADIE bit to 0, ADI can be
cleared.
In addition, ADIE activates the DMAC when an ADI is
generated. At this time, no interrupt to the CPU is
generated.
0: Generation of A/D conversion end interrupt is disabled
1: Generation of A/D conversion end interrupt is enabled
R
Reserved
These bits are always read as 0. The write value should
always be 0.
R/W Trigger Enable
Enables or disables A/D conversion start by the external
trigger input (ADTRG) or A/D conversion start triggers
from the MTU2 and MTU2S (TRGAN, TRG0N, TRG4AN,
and TRG4BN from the MTU2 and TRGAN, TRG4AN, and
TRG4BN from the MTU2S). For selection of the external
trigger and A/D conversion start trigger from the MTU2 or
MTU2S, see the description of the EXTRG bit.
0: A/D conversion start by the external trigger or an A/D
conversion start trigger from the MTU or MTU2S is
disabled
1: A/D conversion start by the external trigger or an A/D
conversion start trigger from the MTU2 or MTU2S is
enabled
