2) The MAX1385/MAX1386 then transmit the contents
of the last register accessed starting with the most
significant 8-bit byte of the 16-bit word. MSBs are
sent first. Afterwards, the master needs to send an
ACK bit.
3) The MAX1385/MAX1386 transmit the least signifi-
cant 8-bit byte of the 16-bit word. MSBs are sent
first.
4) The master issues a NACK bit and then generates a
repeated START or STOP condition (Sr or P).
Poll the current register by omitting step 4 and continu-
ing to issue ACK bits after each data byte.
Stringing Commands
The MAX1385/MAX1386 allow commands to be strung
together to minimize configuration time, which is espe-
cially useful in HS mode. Figure 12 shows an example
of stringing a write and read command together to form
a write/readback command.
Figure 13 shows another useful sequence for a read-
modify-write application.
Slave Address Byte
The MAX1385/MAX1386 include a 7-bit-long slave
address. The first 4 bits (MSBs) of the slave address
are factory programmed and always 0x4h. The logic
state of the address inputs (A2, A1, and A0) determine
the 3 LSBs of the device address (see Figure 14).
Connect A2, A1, and A0 to DV DD or DGND. A maxi-
mum of eight MAX1385/MAX1386 devices can be con-
nected on the same bus at one time using these
address inputs.
The 8th bit of the address byte is a R/ W bit. The
address byte R/ W bit is set to 0 to notify the device that
a command byte will be written to the device next. The
address byte R/ W bit is set to 1 to notify the device that
a control byte will not be sent and to immediately send
data from the last accessed register.
