Figure 8-12. Burst Data Write to Multiple Registers

Configuration register changes will not be accepted when using auto increment writes. For configuration register

changes it is recommended to use a single register write without auto increment.

8.5.2.4 Read Operations

Data is read from the TMP126 by setting the R/W bit of the command word to logic '1'. Data can be continuously

read from a single register by setting the auto-increment bit to '0' in the command register. Figure 8-13 shows an

example of a repeated data read from a single register. Repeated temperature reads are not supported.

Figure 8-13. Repeated Data Read from a Single Register

Figure 8-14 shows how setting the auto increment to logic '1' to can enable a read from multiple registers in a

single transaction. The status register of the TMP126 will not be cleared in burst data read mode. To clear status
