SBAS856D June 2017 – May 2019 DAC8740H , DAC8741H
PRODUCTION DATA.
The DAC874xH implements a Jabber Inhibitor feature in FOUNDATION Fieldbus or PROFIBUS PA modes that prevents the encoder from continuously transmitting data on the bus for longer than a programmed threshold controlled by the UART or SPI interface. In SPI mode, this threshold is programmed by the PAFF_JABBER register. In UART mode, this threshold is programmed by the four-byte initialization sequence before each transmission. This information is described in further detail in the Device Functional Modes and Register Maps sections.
