Description

Reserved—write with zero.
256-bit frame size (default).
192-bit frame size.
128-bit frame size.
64-bit frame size.
No override of

registers to the
associated serial output registers at the OFIR frequency.
Frame mode.
Simple mode.
When OMODE = 1: 16-bit simple mode. When OMODE = 0: 8-bit frame mode.
When OMODE = 1: 8-bit simple mode. When OMODE = 0: 8-bit frame mode.
Do not invert the ESIO output frame sync (EOFS) pin to produce the internal
output frame sync (OFS) signal.
Invert the EOFS pin to produce the internal OFS signal.
No action.
Output collision error reset: Clear ECOL interrupt.

EDO is in high-impedance state.
EDO is enabled.
EDO is a 3-state driver.
EDO is an open-drain driver.
No action. This bit always reads as zero.
Reset the ESIO output section—the ESIO automatically clears this bit one CLK
cycle after performing the reset.
Do not invert the ESIO output bit clock (EOBC) pin to produce the internal output
bit clock (OBC) signal.
Invert the EOBC pin to produce the OBC signal.
Disable ESIO output section—no output processing.
Enable ESIO output section—output processing.
Output frame interrupt rate is every two complete output frames.
Output frame interrupt rate is every four complete output frames.
Output frame interrupt rate is every eight complete output frames.
Output frame interrupt rate is every sixteen complete output frames.
