16.4 D/A Output Control
In the H8/3048 Series, D/A converter output can be enabled or disabled in software standby mode.
When the DASTE bit is set to 1 in DASTCR, D/A converter output is enabled in software standby
mode. The D/A converter registers retain the values they held prior to the transition to software
standby mode.
When D/A output is enabled in software standby mode, the reference supply current is the same as
during normal operation.
16.5 Usage Notes
When using an D/A converter, note the following.
(1) V_CC ≥ AV_CC – 0.3V
(2) AV_CC ≥ V_REF ≥ ANn ≥ AV_SS = V_SS
(N = 0 to 7)
Note: Restriction for the ZTAT^TM version only; The S Mask version of ZTAT^TM, the Flash
Memory version and Mask ROM version can be used regularly without restriction.
