16 bits of data from a MAX1385/MAX1386 register (see

1) After generating a START condition (S or Sr),

address the MAX1385/MAX1386 by sending the

appropriate slave address byte and its correspond-

ing R/ W bit set to a 0 (see the Slave Address Byte

section). The MAX1385/MAX1386 then answer with

D9 is the MSB.

an ACK bit (see the Acknowledge Bits section).

2) Send the appropriate read command byte (see the

Command Byte section). The MAX1385/MAX1386

answer with an ACK bit.

3) After generating a repeated START condition (Sr),

address the MAX1385/MAX1386 once more by

sending the appropriate slave address byte and its

R/ W bit set to 1. The MAX1385/MAX1386 answer

with an ACK bit.

4) The MAX1385/MAX1386 transmit the most signifi-

cant 8-bit data byte of the 16-bit data word with the

MSB first. Afterwards, the master needs to send an

ACK bit.

5) The MAX1385/MAX1386 transmit the least signifi-

cant 8-bit byte of the 16-bit word with the MSB first.

6) The master issues a NACK bit and then generates a

repeated START or STOP condition (Sr or P).

Continue to poll the current register or read multiple

words (e.g., empty FIFO of several conversion results)

by omitting step 6 and keep issuing ACK bits after each

data byte. Use the following 3-byte sequence to read

16 bits of data from the last accessed MAX1385/

MAX1386 register:

1) After generating a START condition (S or Sr),

address the MAX1385/MAX1386 by sending the

appropriate 7-bit slave address byte and its corre-

sponding R/ W bit set to 1 (see the Slave Address

Byte section). The MAX1385/MAX1386 then answer

with an ACK bit (see the Acknowledge Bits section).
