Usage Notes

18.5.1

Analog Power Supply Current in Power-Down Mode

If this LSI enters a power-down mode such as software standby, watch, subactive, subsleep, and

module stop modes while D/A conversion is enabled, the D/A cannot retain analog outputs within

the given D/A absolute accuracy* although it retains digital values. The analog power supply

current is approximately the same as that during D/A conversion. To reduce analog power supply

current in power-down mode, clear the DAOE0, DAOE1 and DAE bits to 0 to disable D/A outputs

before entering the mode.

Note: * The H8S/2258 Group, H8S/2238B, and H8S/2236B satisfy the specified D/A absolute

accuracy.

18.5.2

Setting for Module Stop Mode

It is possible to enable/disable the D/A converter operation using the module stop control register,

the D/A converter does not operate by the initial value of the register. The register can be accessed

by releasing the module stop mode. For more details, see section 24, Power-Down Modes.
