Data Byte (Read Cycle)
A read cycle must be initiated to obtain conversion
results. Read cycles begin with the bus master issuing
a START condition followed by 7 address bits and a
read bit (R/W = 1). If the address byte is successfully
received, the MAX11646/MAX11647 (slave) issue an
acknowledge. The master then reads from the slave.
The result is transmitted in 2 bytes; first 6 bits of the first
byte are high, then MSB through LSB are consecutively
clocked out. After the master has received the byte(s),
it can issue an acknowledge if it wants to continue
reading or a not-acknowledge if it no longer wishes to
read. If the MAX11646/MAX11647 receive a not-
acknowledge, they release SDA, allowing the master to
generate a STOP or a repeated START condition. See
the
Clock Modes and Scan Mode sections for detailed
information on how data is obtained and converted.
Clock Modes
The clock mode determines the conversion clock and
the data acquisition and conversion time. The clock
mode also affects the scan mode. The state of the set-
up byte’s CLK bit determines the clock mode (Table 1).
At power-up, the MAX11646/MAX11647 are defaulted
to internal clock mode (CLK = 0).
