(s[3][2]),(s[3][3]),

(n[0]),(n[1]),(n[2]),(n[3]),

s: Each of these four 32-bit status/data values

has the following structure:

The three most significant bits of a status/data

value indicates the data polarity and conversion

state. The remaining 29 bits are the conversion

result.

Bits 31 and 30 are always LOW.

SN: bit 29 is the conversion result sign indicator.

If VIN is >0, this bit is HIGH. If VIN is <0, this

bit is LOW.

Data: bit 28 is the most significant bit (msb) of

the result. This bit, in conjunction with Bit 29,

also indicates an underrange or overrange

condition. If bits 29 and 28 are both HIGH, the

channel’s differential input voltage is above +FS

(full scale). If bits 29 and 28 are both LOW, the

input voltage is below –FS.

8.7.3 SetVoltages

Function Programs the output power voltages for all four

channels.

Opcode 0x02

Command (Volts<7:0>)

Volts is an 8-bit value, passed LSB first, that is

composed of bit fields that specify the output

voltages. It has the following structure:

Response none

Notes Once set, the output voltages apply until they are

changed by another SetVoltanges action or a

module reset occurs.

After a module reset, all power outputs default to

1.25V output.

8.7.4 ReadEeprom

Function Returns a byte value from the module’s

non-volatile memory.

Opcode 0x0D

Command (Adrs)

Response (Data)

Notes This function is used by the middleware to store

calibration data for the module. Refer to the

distribution media for details.

8.7.5 WriteEeprom

Function Stores a byte value in the module’s non-volatile

memory.

Opcode 0x0E

Parameter Function

s[] Array of four 32-bit status/data

values, LSB first, associated with

analog input channels 0 (first) to 3

(last).

n[] Array of four 8-bit sample

numbers, LSB first, associated

with analog input channels 0 (first)

to 3 (last).

Parameter Function

Volts Four 2-bit fields that specify the

output voltages. Each bit field

corresponds to one channel.
