4.1 DADR: D/A Data Register
The D/A Data Register sets the output voltage of the D/A converter.
• DADR0(ch0): Address 0364
H
(Access:
Byte, Half-word
)
• DADR1(ch1): Address 0366
H
(Access:
Byte, Half-word
)
(For the attributes, refer to the “
Meaning of Bit Attribute Symbols (Page No.10)
”.)
• The D/A Data Register is not initialized on a reset.
• The setting is “000
H
” - “3FF
H
”.
4.2 DACR: D/A Control Register
The D/A Control Register controls whether D/A converter output is enabled or disabled.
• DACR(ch0/ch1): Address 0361
H
(Access:
Byte
)
(For the attributes, refer to the “
Meaning of Bit Attribute Symbols (Page No.10)
”.)
• bit7-3: Undefined
At write, always write “0”. At read, the read value is indeterminate.
• bit0: D/A output control
• Enables a converted analog level to be output from the DA pin.
(To place the DA0 pin in the output state, it is necessary to set PFR28.6=“1”.
• The D/A output equals 0.0 V when the
D/A output control
bit is “0”.
• bit1: D/A output control
• Enables a converted analog level to be output from the DA pin.
(To place the DA1 pin in the output state, it is necessary to set PFR28.7=“1”.
• The D/A output equals 0.0 V when the
D/A output control
bit is “0”.
