Description
15—12
11—10
Reserved—write with zero.
256-bit frame size (default).
192-bit frame size.
128-bit frame size.
64-bit frame size.
No override of
ICSL
0—1
register transfer rate control.
Override
ICSL
0—1
register transfer rate control by transferring all channel input
shift registers to the associated
IDMX
0—15
registers at the IFIR frequency.
Select frame mode.
Select simple mode.
16-bit mode:
IDMX
0—15
registers start shift-in at bit 15.
8-bit mode:
IDMX
0—15
registers start shift-in at bit 7.
No action.
Synchronize internal input frame sync (IFS) with the ESIO input bit clock (EIBC)
pin.
Do not invert the ESIO input frame sync (EIFS) pin to produce the internal input
frame sync (IFS) signal.
Invert the EIFS pin to produce the internal IFS signal.
No action. This bit always reads as zero.
Reset the ESIO input section—the ESIO automatically clears this bit one CLK
cycle after performing the reset.
Do not invert the ESIO input bit clock (EIBC) pin to produce the internal input bit
clock (IBC) signal.
Invert the EIBC pin to produce the internal IBC signal.
Disable ESIO input section—no input processing.
Enable ESIO input section—input processing.
Input frame interrupt rate is every two complete input frames.
Input frame interrupt rate is every four complete input frames.
Input frame interrupt rate is every eight complete input frames.
Input frame interrupt rate is every sixteen complete input frames.
