Writing to the TSE2002B3C Temperature Register Set is accomplished through a modified block write operation for two (2) data bytes. To maintain
Reading data from the TS may be accomplished in one of two ways:
1. If the location latched in the Pointer Register is correct (for normal operation it is expected the same address will be read repeatedly for temper-
2. The pointer register is loaded with the correct register address, and the data is read. The sequence to preset the pointer register is shown in the
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)
