Zarlink Semiconductor Inc.
The constant delay mode is controlled by V/C (bit 14) in the Connection Memory Low when CMM = 0. When this bit
is set low, the channel is in constant delay mode. If VAREN (bit 4) in the Control Register (CR) is set (to enable
variable throughput delay on a chip-wide basis), the device can still be programmed to operate in constant delay
mode.

10.0 Connection Memory Description
The connection memory consists of two blocks, Connection Memory Low (CM_L) and Connection Memory High
(CM_H). The CM_L is 16 bits wide and is used for channel switching and other special modes. The CM_H is 5 bits
wide and is used for the voice coding function. When UAEN (bit 15) of the Connection Memory Low (CM_L) is low,
μ
-law/A-law conversion will be turned off and the contents of CM_H will be ignored. Each connection memory
location of the CM_L or CM_H can be read or written via the 16 bit microprocessor port within one microprocessor
access cycle. See Table 32 on page 53 for the address mapping of the connection memory. Any unused bits will be
reset to zero on the 16-bit data bus.
For the normal channel switching operation, CMM (bit 0) of the Connection Memory Low (CM_L) is programmed
low. SCA7 - 0 (bits 8 - 1) indicate the source (input) channel address and SSA4 - 0 (bits 13 - 9) indicate the source
(input) stream address. The 5-bit contents of the CM_H will be ignored during the normal channel switching mode
without the
μ
-law/A-law conversion when UAEN (bit 15) of the Connection Memory Low (CM_L) is set to zero. If
μ
-law/A-law conversion is required, the CM_H bits must be programmed first to provide the voice/data information,
the input coding law and the output coding law before the assertion of UAEN (bit 15) in the Connection Memory
Low.
When CMM (bit 0) of the Connection Memory Low (CM_L) is programmed high, the ZL50023 will operate in one of
the special modes described in Table 34 on page 55. When the per-channel message mode is enabled, MSG7 - 0
(bit 10 - 3) in the Connection Memory Low (CM_L) will be output via the serial data stream as message output data.
When the per-channel message mode is enabled, the
μ
-law/A-law conversion can also be enabled as required.
