Read Alarm Register

(Command Code 0001)

The Read Alarm Register command, 0001, outputs the

current status of the alarm register (see Table 11). The

address bits in this command are ignored. The alarm

illustrates the encoding of the alarm register.

After receiving an interrupt, read the alarm register to

determine the source of the interrupt (see the

Alarm

Read Current Data Register for Selected

Channel (Command Code 0010)

The Read Current Data Register for Selected Channel

command, 0010, outputs the data in the current data

lowing this command select the input channel to be

read (see Table 3). The current data register is a 10-bit

Output Data Format and Current Data Registers sec-

tions for more details. See Table 3 for channel address-

es. Also, see Figure 7.

Read Current Data Register for All

Channels (Command Code 0011)

The Read Current Data Registers for All Channels com-

mand, 0011, outputs the data in the current data regis-

ters of all 10 channels, starting with the internal

temperature sensor, then the VDD monitor, followed by

AIN0 to AIN7. The address bits following this command

are ignored. It takes 20 bytes to read all of the 10 chan-

nels’ current data registers.

Read Configuration Register for Selected

Channel (Command Code 0100)

The Read Configuration Register for Selected Channel

command, 0100, outputs the configuration data of the

channel selected by the address bits (see Table 3).

The first register that shifts out is the upper threshold

ter (2 bytes), ending with the channel configuration reg-

ister (1 byte), all MSB first. It takes 5 bytes to read all

three registers. See the

Channel Registers section for

more details.
