USER INTERFACE TO OTHER ON-CHIP ADuC816
PERIPHERALS
The following section gives a brief overview of the various
peripherals also available on-chip. A summary of the SFRs used
to control and configure these peripherals is also given.
DAC
The ADuC816 incorporates a 12-bit, voltage output DAC
on-chip. It has a rail-to-rail voltage output buffer capable of
driving 10 k
Ω/100 pF. It has two selectable ranges, 0 V to V
REF
(the internal bandgap 2.5 V reference) and 0 V to AVDD. It can
operate in 12-bit or 8-bit mode. The DAC has a control regis-
ter, DACCON, and two data registers, DACH/L. The DAC
output can be programmed to appear at Pin 3 or Pin 12. It
should be noted that in 12-bit mode, the DAC voltage output
will be updated as soon as the DACL data SFR has been writ-
ten; therefore, the DAC data registers should be updated as
DACH first followed by DACL.

DACPIN
DAC Output Pin Select.
Set by the user to direct the DAC output to Pin 12 (P1.7/AIN4/DAC).
Cleared by user to direct the DAC output to Pin 3 (P1.2/DAC/IEXC1).
3
DAC8
DAC 8-bit Mode Bit.
Set by user to enable 8-bit DAC operation. In this mode the 8-bits in DACL SFR are routed to
the 8 MSBs of the DAC and the 4 LSBs of the DAC are set to zero.
Cleared by user to operate the DAC in its normal 12-bit mode of operation.
2
DACRN
DAC Output Range Bit.
Set by user to configure DAC range of 0 – AVDD.
Cleared by user to configure DAC range of 0 – 2.5 V.
1
DACCLR
DAC Clear Bit.
Set to “1” by user to enable normal DAC operation.
Cleared to “0” by user to reset DAC data registers DACl/H to zero.
0
DACEN
DAC Enable Bit.
Set to “1” by user to enable normal DAC operation.
Cleared to “0” by user to power-down the DAC.
DACH/L
DAC Data Registers
Function
DAC Data Registers, written by user to update the DAC output.
SFR Address
DACL (DAC Data Low Byte)
–>FBH
DACH (DAC Data High Byte)
–>FCH
Power-On Default Value
00H
–>Both Registers
Bit Addressable
No
–>Both Registers
The 12-bit DAC data should be written into DACH/L right-justified such that DACL contains the lower eight bits, and the lower
nibble of DACH contains the upper four bits.
