• Description: Analog Line Interface Solution ALIS
• Manufacturer: Siemens Semiconductor Group

6.1.1
• 6 Configuration registers:
• 8 Extended registers:
• 1 Coefficient RAM:
• 1 Caller ID RAM:
6.2
The SOP (status operation) command allows the ALIS status registers to be written or
read via the µ-controller interface.
PU Power-up operation command (only with SOP write command)
RW Read/Write: Enables reading from ALIS or writing information to ALIS
LSEL Length select information (see also programming procedure)
LSEL = 000:1 byte of data follows (CR0)
LSEL = 001:2 bytes of data follow (CR1, CR0)
LSEL = 010:3 bytes of data follow (CR2. CR1, CR0)
LSEL = 011:4 bytes of data follow (CR3, CR2. CR1, CR0)
LSEL = 100:5 bytes of data follow (CR4, CR3, CR2, CR1, CR0)
LSEL = 101:6 bytes of data follow (CR5, ...., CR1, CR0)
Note: If only one configuration register requires modification, for example CR3, this can
be accomplished by setting LSEL=011 and releasing pin CS after CR3 is written, to.
