Appropriate commands via the serial µ-controller interface enable very flexible
programming and verification of ALIS.
Four different commands are used to access the various control registers and RAMs:
SOP (see page 38), XOP (see page 44), COP (see page 50) and CAO (see page 51).
The first byte received via DIN selects the command type. Each command can be used
as a write or read command. Thanks to the extended ALIS control facilities, the SOP,
XOP and COP commands contain additional information for programming (writing) and
verifying (reading) the ALIS status (e.g. number of subsequent bytes, software reset,
operating mode).
Up to 8 bytes of data can be read or written with an SOP, XOP or COP command. The
CAO command allows all 512 bytes of the caller ID RAM to be read or written. Any read
command causes ALIS to respond with its specific identification byte before sending the
requested information.
