DS1624
f 1
The configuration register is defined as follows:
CONFIGURATION/STATUS REGISTER
where:
DONE = Conversion Done bit, 1 = Conversion complete, 0 = conversion in progress.
1SHOT = One Shot Mode. If 1SHOT is 1 , the DS1624 will perform one temperature conversion upon
receipt of the Start Convert T protocol. If 1SHOT is 0 , the DS1624 continuously performs temperature
conversions. This bit is nonvolatile and the DS1624 is shipped with 1SHOT = 0.
Since the configuration register is implemented in E
2
, writes to the register require 10ms to complete.
After issuing a command to write to the configuration register, no further accesses to the DS1624 should
be made for at least 10ms.
OPERATIONMEMORY
Byte Program Mode
In this mode, the master sends addresses and one data byte to the DS1624.
Following a START condition, the device code (4-bit), the slave address (3-bit), and the R/
bit (which
is logic-low) are placed onto the bus by the master. The master then sends the Access Memory protocol.
This indicates to the addressed DS1624 that a byte with a word address will follow after it has generated
an acknowledge bit. Therefore, the next byte transmitted by the master is the word address and will be
written into the address pointer of the DS1624. After receiving the acknowledge of the DS1624, the
master device transmits the data word to be written into the addressed memory location. The DS1624
acknowledges again and the master generates a STOP condition. This initiates the internal programming
cycle of the DS1624. A repeated START condition, instead of a STOP condition, will abort the
programming operation.
During the programming cycle the DS1624 does not acknowledge any further accesses to the device until
the programming cycle is complete (no longer than 50ms.)
Page Program Mode
To program the DS1624 the master sends addresses and data to the DS1624, which is the slave. This is
done by supplying a START condition followed by the 4-bit device code, the 3-bit slave address, and the
R/
bit which is defined as a logic-low for a write. The master then sends the Access Memory protocol.
This indicates to the addressed slave that a word address will follow. The slave outputs the acknowledge
pulse to the master during the ninth clock pulse. When the word address is received by the DS1624 it is
placed in the address pointer defining which memory location is to be written. The DS1624 will generate
an acknowledge after every 8 bits received and store them consecutively in an 8-byte RAM until a STOP
condition is detected which initiates the internal programming cycle.
A repeated START condition, instead of a STOP condition, will abort the programming operation.
During the programming cycle the DS1624 does not acknowledge any further accesses to the device until
the programming cycle is complete (no longer than 50ms).
