JAJSNM5A December 2021 – August 2022 TMP9R00-SP
PRODUCTION DATA
Block reads can be initiated by setting the pointer register to 80h to 87h. The temperature results are mirrored at pointer addresses 80h to 88h; temperature results for all the channels can be read with one read transaction. Setting the pointer register to any address from 80h to 88h signals to the TMP9R00-SP device that a block of more than two bytes must be transmitted before a design stop is issued. In block read mode, the TMP9R00-SP device auto increments the pointer address. After 88h, the pointer resets to 80h. The controller must NACK the last byte read so the TMP9R00-SP device can discontinue driving the bus, which allows the controller to initiate a stop. In this mode, the pointer continuously loops in the address range from 80h to 88h, so the register may be easily read multiple times. Block read does not disrupt the conversion process.
