23.5
23.5.1
Operation of the D/A converter can be disabled or enabled using the module stop control register.
The initial setting is for operation of the D/A converter to be halted. Register access is enabled by
clearing the module stop state. For details, refer to section 28, Power-Down Modes.
23.5.2
When this LSI makes a transition to software standby mode with D/A conversion enabled, the
D/A outputs are retained, and the flow of current from the analog power supply remains the same
as during D/A conversion. If the analog power-supply current has to be reduced in software
standby mode, clear the DAOE0, DAOE1, and DAE bits to 0 to disable D/A conversion.
23.5.3
When this LSI makes a transition to deep software standby mode with D/A conversion enabled,
the D/A outputs enter high-impedance state.
23.5.4
The limitations described below apply to emulation of the 10-bit D/A converter.
In emulation with the full-spec emulator (E6000H), the resolution of the analog output becomes
eight bits, and the precision of D/A conversion is not guaranteed. Furthermore, when DADR01T is
read, the values in emulation differ from those for the actual product. Thus, as a precondition for
emulation with the full-spec emulator (E6000H), do not read DADR01T.
No particular limitations apply to emulation with the on-chip emulator (E10A-USB).
The above notes are summarized in table 23.3 below.
