6.12 HSSO Interface
6.12.1
6.12.2
The High Speed Serial Output (HSSO) is a standard 3-line
output interface implemented to give out data bursts in a
multiplexed way. Up to 4 applications can be given out
simultaneously:

The HSSO can be configured using the ’set HSSO / RS232
configuration’ MC command (see section 8). Each HSSO
burst consists of a header word followed by n data words
(as indicated in the header).
