DS1672
8 of 12
The DS1672 may operate in the following two modes:
1.
Slave receiver mode (DS1672 write mode):
Serial data and clock are received through SDA and
SCL. After each byte is received, an acknowledge bit is transmitted. START and STOP conditions
are recognized as the beginning and end of a serial transfer. Address recognition is performed by
hardware after reception of the slave address and direction bit. The slave address byte is the first byte
received after the START condition is generated by the master. The slave address byte contains the
7-bit DS1672 address, which is 1101000, followed by the direction bit (R/
W
), which for a write is a
0. After receiving and decoding the slave address byte the DS1672 outputs an acknowledge on the
SDA line. After the DS1672 acknowledges the slave address + write bit, the master transmits a
register address to the DS1672. This will set the register pointer on the DS1672. The master will
then begin transmitting each byte of data with the DS1672 acknowledging each byte received. The
master will generate a STOP condition to terminate the data write.
2.
Slave transmitter mode (DS1672 read mode):
The first byte is received and handled as in the slave
receiver mode. However, in this mode, the direction bit will indicate that the transfer direction is
reversed. Serial data is transmitted on SDA by the DS1672 while the serial clock is input on SCL.
START and STOP conditions are recognized as the beginning and end of a serial transfer. Address
recognition is performed by hardware after reception of the slave address and direction bit. The slave
address byte is the first byte received after the START condition is generated by the master. The
slave address byte contains the 7-bit DS1672 address, which is 1101000, followed by the direction bit
(R/
W
), which for a read is a 1. After receiving and decoding the slave address byte the DS1672
outputs an acknowledge on the SDA line. The DS1672 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
DS1672 must receive a “not acknowledge” to end a read.
