C-bus interface
The data registers in this device are selected by the Pointer Register. At power-up, the
Pointer Register is set to 00h, the location for the Capability Register. The Pointer
Register latches the last location to which it was set. Each data register falls into one of
three types of user accessibility:
" Read only
" Write only
" Write/Read same address
A write to this device will always include the address byte and the pointer byte. A write to
any register other than the Pointer register requires two data bytes.
Reading this device can take place either of two ways:
" If the location latched in the Pointer register is correct (most of the time it is expected
that the Pointer register will point to one of the Temperature register (as it will be the
data most frequently read), then the read can simply consist of an address byte,
followed by retrieving the two data bytes.
" If the Pointer register needs to be set, then an address byte, pointer byte,
repeat START, and another address byte will accomplish a read.
The data byte has the most significant bit first. At the end of a read, this device can accept
either Acknowledge (ACK) or No Acknowledge (NACK) from the Master (No Acknowledge
is typically used as a signal for the slave that the Master has read its last byte). It takes
this device 125 ms to measure the temperature. Refer to timing diagrams Figure 6
to
Figure 9
for how to program the device.
