If A1 is not connected in the demultiplexed mode neither an access to the CMR, CST
nor a read access to the MOD register is possible.
In this case A1 is fixed to ground internally.
Five directly addressable registers are provided:
• Mode register (MOD)
• Status register (STA)
• Conference Status register (CST)
• Conference Mask Register (CMR)
• Indirect Access Register (IAR)
Two other registers and the control memories are accessed by a simple three byte
indirect access method:
• Configuration Register (CFR)
• Clock Shift Register (CSR)
• Connection Memory (CM)
• Conference Control Memory (CCM)
The status register (STA) and the conference status register (CST) are read-only-
registers, the conference mask register (CMR) is a write-only-register; MOD, CFR, CSR,
IAR and CM or CCM can be read or written. An indirect access scheme is used to access
the CFR, CSR, CM or CCM using the indirect access register (IAR).
The following direct registers may be accessed:
