PROGRAMMING EXAMPLES
The following programming examples illustrate a typical
sequence of events for various features of the AD5231. See
Table 7 for the instructions and data-word format. The
instruction numbers, addresses, and data appearing at SDI
and SDO pins are in hexadecimal format.
Table 13. Scratchpad Programming
SDI
SDO
Action
0xB00100
0xXXXXXX
Writes data 0x100 into RDAC register,
Wiper W moves to 1/4 full-scale position.
Table 14. Incrementing RDAC Followed by Storing the
Wiper Setting to EEMEM
SDI
SDO
Action
0xB00100
0xXXXXXX
Writes data 0x100 into RDAC register,
Wiper W moves to 1/4 full-scale
position.
0xE0XXXX
0xB00100
Increments RDAC register by one to
0x101.
0xE0XXXX
Increments RDAC register by one to
0x102. Continue until desired wiper
position is reached.
0x20XXXX
0xXXXXXX
Stores RDAC register data into
EEMEM(0). Optionally tie WP to GND
to protect EEMEM values.
The EEMEM value for the RDAC can be restored by power-on,
by strobing the PR pin, or by programming, as shown in
Table 15. Restoring the EEMEM Value to the RDAC Register
SDI
SDO
Action
0x10XXXX
0xXXXXXX
Restores the EEMEM(0) value to the
RDAC register.
0x00XXXX
0x10XXXX
NOP. Recommended step to minimize
power consumption.
Table 16. Using Left-Shift by One to Increment 6 dB Step
SDI
SDO
Action
0xC0XXXX
0xXXXXXX
Moves the wiper to double the
present data contained in the RDAC
register.
Table 17. Storing Additional User Data in EEMEM
SDI
SDO
Action
0x32AAAA
0xXXXXXX
Stores data 0xAAAA in the extra
EEMEM location USER1. (Allowable to
address in 14 locations with a
maximum of 16 bits of data.)
0x335555
0x32AAAA
Stores data 0x5555 in the extra
EEMEM location USER2. (Allowable to
address in 14 locations with a
maximum of 16 bits of data.)
Table 18. Reading Back Data from Memory Locations
SDI
SDO
Action
0x92XXXX
0xXXXXXX
Prepares data read from EEMEM(2)
location.
0x00XXXX
0x92AAAA
NOP Instruction 0 sends a 24-bit word
out of SDO, where the last 16 bits
contain the contents in the EEMEM(2)
location. The NOP command ensures
that the device returns to the idle
power dissipation state.
Table 19. Reading Back Wiper Settings
SDI
SDO
Action
0xB00200
0xXXXXXX
Writes RDAC to midscale.
0xC0XXXX
0xB00200
Doubles RDAC from midscale to full
scale (left-shift instruction).
0xA0XXXX
0xC0XXXX
Prepares reading wiper setting from
RDAC register.
0xXXXXXX
0xA003FF
Reads back full-scale value from SDO.
