Acknowledge Bits
Data transfers are acknowledged with an acknowledge
bit (ACK) or a not-acknowledge bit (NACK). Both the
master and the MAX1385/MAX1386 generate ACK bits.
To generate an ACK, SDA must be pulled low before
the rising edge of the ninth clock pulse and kept low
during the high period of the ninth clock pulse (see
Figure 20). To generate a NACK, SDA is pulled high
before the rising edge of the ninth clock pulse and is
left high for the duration of the ninth clock pulse.
Monitoring NACK bits allow for detection of unsuccess-
ful data transfers. NACK bits can also be used by the
master to interrupt the current data transfer to start
another data transfer. The MAX1385/MAX1386 do not
issue an ACK after the last byte of a full reset write to
the Software Clear register.
Fast/High-Speed Modes
At power-up, the bus timing is set for slow-/fast-speed
mode (FS mode), which allows bus speeds up to
400kHz. The MAX1385/MAX1386 are configurable for
42
