7.6 BADR4
The I/O Region defined by BADR4 contains the DAC0 and DAC1 data registers.
7.6.1 DAC0 DATA REGISTER
BADR4 + 0
WRITE
DAC0(0)DAC0(1)DAC0(2)DAC0(3)DAC0(4)DAC0(5)DAC0(6)DAC0(7)DAC0(8)DAC0(9)DAC0(10)DAC0(11)
----
0123456789101112131415
MSB LSB
Writing to this register will initiate data conversion on DAC0. If the
MODE
bit
in BADR1+8
is set, writes to this register will provide a simultaneous update of both DAC0 and DAC1 with the data written to this regis-
ter.
The data format is dependent upon the offset mode described below:
Bipolar Mode
: Offset Binary Coding
000 h = -FS
7FFh = Mid-scale
(0V)
FFFh = +FS - 1LSB
Unipolar
Mode
:
Straight Binary Coding
000 h = -FS (0V)
7FFh = Mid-scale (+FS/2)
FFFh = +FS - 1LSB
7.6.2 DAC1 DATA REGISTER
BADR4 + 2
WRITE
DAC1(0)DAC1(1)DAC1(2)DAC1(3)DAC1(4)DAC1(5)DAC1(6)DAC1(7)DAC1(8)DAC1(9)DAC1(10)DAC1(11)
----
0123456789101112131415
MSB LSB
Writing to this register will initiate data conversion on DAC1. If the
MODE
bit
in BADR1+8
is set, writes to this register will have no effect
