Function
Data Downstream Output, IOM or PCM
configuration.
Serial Interface Port, SLD configuration.
Depending on the bit OMDR:COS these lines
have push pull or open drain characteristic.
For unassigned channels or when bit
OMDR:CSB is reset the pins are in the high
impedance state.
* Note: EPIC-1 only
Address bus in the demultiplexed P interface
mode.
Supply voltage: 5 V
Ground: 0 V
