Example 7: Self-Test Conversion on All Parts
Example 7 shows a self-test conversion routine for all parts in a
daisy chain.
7.
The CNVST control register should be programmed to
gate the CNVST signal on all parts. The 32-bit write
command is 0x03A0340A (see Table 29 , Write 5). This
1.
2.
To select the self-test conversion, set Bits[D15:D14] of the
control register to 1, and set Bits[D13:D12] of the control
register to 0 on all parts. The 32-bit write command is
0x01B81092 (see Table 29, Write 1).
Set Bit D0 of the control register to 1 on all parts. This
setting enables the daisy-chain register read operation on
all parts. The 32-bit write command is 0x01C2B6E2 (see
8.
write prevents unintentional conversions from being
initiated by noise or glitches on the CNVST pin. This write
also updates the on-chip output registers of all devices in
the daisy chain.
Apply a CS low pulse that frames 32 SCLKs to read back
the desired voltage. This frame should simultaneously
write the 32-bit command 0xF800030A, as described in
the Serial Interface section (see Table 29 , Write 6).
3.
The register address corresponding to the self-test
conversion should be written to the read register of all
parts (see Table 13 for register addresses). The 32-bit write
command is 0x038617CA (see Table 29, Write 3).
Example 8: Software Reset on All Parts
Example 8 shows a software reset routine for all parts in a
daisy chain.
4.
5.
6.
Program the CNVST control register to 0x02 on all parts
to allow conversions to be initiated using the CNVST pin.
Write 4).
Initiate conversions through the falling edge of CNVST.
Allow sufficient time for the self-test conversions to be
1.
2.
Set Bit D7 of the control register to 1 on all parts to place
the AD7280A into software reset. The 32-bit write command
is 0x01D2B412 (see Table 30, Write 1).
Set Bit D7 of the control register to 0 on all parts to take the
AD7280A out of software reset. The 32-bit write command
is 0x01C2B6E2 (see Table 30, Write 2).
