4 Revision History
NOTE: Page numbers for previous revisions may differ from page numbers in the current version.
Changes from Revision A (August 2017) to Revision B
Page
• Changed Functional Block Diagram's GND and GNDP pin designators for correct grounding of the Output Driver. ......... 11
• Updated tablenotes of Table 3 ............................................................................................................................................. 38
• Added sentence: USART Synchronous Mode is identical to a Serial Peripheral Interface (SPI) without a chip-select
because the addressing is handled by the three-bit UART_ADDR value to enable up to eight devices on a single bus. .. 43
• Added sentence: The temperature measurement's sample and conversion time requires at least 100 us after the
temperature measurement command is issued. Do not send other commands during this time to allow the
temperature value to properly update................................................................................................................................... 51
Changes from Original (April 2017) to Revision A
Page
• Added zero padding information to the CONFIGURATION/STATUS Command section.................................................... 32
• Changed UART interface parameter text from: 1 stop bit to: 2 stop bit .............................................................................. 34
• Changed interfield wait time text from: optional to: required for 1 stop bit ........................................................................... 34
• Added sentence: The sync field (0x55) is not included as part of the checksum calculation. ............................................. 37
• Updated content and added tablenotes to Table 3 .............................................................................................................. 38
• Added sentence: The diagnostic field is included in the slave generated checksum calculation. ...................................... 41
• Added subsection Direct Data Burst Through USART Synchronous Mode......................................................................... 47
• Added Equation 8 ................................................................................................................................................................. 52
• Added sentence: This includes all threshold timing and level values. ................................................................................ 54
