Bit 6—D/A Output Enable 0 (DAOE0): Controls D/A conversion and analog output for channel

Bit 6

DAOE0

Description

Analog output DA0 is disabled

(Initial value)

Channel 0 D/A conversion is enabled; analog output DA0 is enabled

Bit 5—D/A Enable (DAE): The DAOE0 and DAOE1 bits both control D/A conversion. When

the DAE bit is cleared to 0, the channel 0 and 1 D/A conversions are controlled independently.

When the DAE bit is set to 1, the channel 0 and 1 D/A conversions are controlled together.

Output of resultant conversions is always controlled independently by the DAOE0 and DAOE1

bits.

Bit 7

DAOE1

Bit 6

DAOE0

Bit 5

DAE

Description

Channel 0 and 1 D/A conversions disabled

Channel 0 D/A conversion enabled

Channel 1 D/A conversion disabled

Channel 0 and 1 D/A conversions enabled

Channel 0 D/A conversion disabled

Channel 1 D/A conversion enabled

Channel 0 and 1 D/A conversions enabled

Legend: *: Don’t care

If the H8S/2350 Group enters software standby mode when D/A conversion is enabled, the D/A

output is held and the analog power current is the same as during D/A conversion. When it is

necessary to reduce the analog power current in software standby mode, clear both the DAOE0

and DAOE1 bits to 0 to disable D/A output.

Bits 4 to 0—Reserved: Read-only bits, always read as 1.
