from the Master (No Acknowledge is typically used as a signal for the slave that the Master has read its last byte).
Reads/writes on the device registers will not affect the EVENT# output in comparator mode. The EVENT# signal will remain asserted until the
The TS3000B3A temperature sensor circuitry continuously monitors the temperature and updates the temperature data minimum of eight times
Internal registers are used to configure both the TS performance and response to over-temperature conditions. The device contains programmable
The data registers in this device are selected by the Pointer Register. At power-up the Pointer Register is set to “00”, the location for the Capability
1. Read only
2. Write only
3. 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
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 Read
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 (No Ack)
