Usage Notes

23.5.1

Module Stop State Setting

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

D/A Output Hold Function in Software Standby Mode

When this LSI makes a transition to software standby mode with D/A conversion enabled, the

D/A outputs are retained, and the analog power supply current is equal to as during D/A

conversion. If the analog power supply current needs to be reduced in software standby mode,

clear the DAOE0, DAOE1 and DAE bits all to 0 to disable D/A conversion.

23.5.3

Notes on Deep Software Standby Mode

When this LSI makes a transition to deep software standby mode, the D/A outputs enter high-

impedance state.
