2) Slave transmitter mode (DS32B35/DS32C35 read
mode): The first byte is received and handled as in
the slave receiver mode. However, in this mode, the
direction bit indicates that the transfer direction is
reversed. The device transmits serial data on SDA
while the serial clock is input on SCL. START and
STOP conditions are recognized as the beginning
and end of a serial transfer (see Figure 4). The slave
address byte is the first byte received after the mas-
ter generates the START condition. The slave
address byte contains one of the 7-bit device
addresses. The slave address is 1101000 for the
RTC. For the DS32B35 FRAM, the first four bits are
1010, and the next three bits select one of eight
blocks of data (see Table 2). Each slave address is
followed by the direction bit (R/W), which is one for a
read. After receiving and decoding the slave address
byte, the device outputs an acknowledge on the SDA
line. The device then begins to transmit data starting
with the register address pointed to by the register
pointer. If the register pointer is not written to before
the initiation of a read mode, the first address that is
read is the last one stored in the register pointer. The
device must receive a "not acknowledge" to end a
read. The register pointer can be set prior to a data
read by initiating a slave receiver mode sequence,
with no data bytes transmitted after the register
address data.
