25.0
25.1
When A13 is high, the data or connection memory can be accessed by the microprocessor port. Bit 1 - 0 in the
Control Register determine the access to the data or connection memory (CM_L or CM_H).
25.2
When the CMM bit (bit 0) in the connection memory low is zero, the per-channel transmission is set to the normal
channel-switching. The connection memory low bit assignment for the channel transmission mode is shown in
Table 52 on page 80.
Notes:
1. A13 must be high for access to data and connection memory positions. A13 must be low to access internal registers.
2. Channels 0 to 31 are used when serial stream is at 2.048 Mbps.
3. Channels 0 to 63 are used when serial stream is at 4.096 Mbps.
4. Channels 0 to 127 are used when serial stream is at 8.192 Mbps.
5. Channels 0 to 255 are used when serial stream is at 16.384 Mbps.

Conversion between µ-law and A-law Enable
When this bit is low, normal switch without µ-law/A-law conversion. Connec-
tion memory high will be ignored.
When this bit is high, switch with µ-law/A-law conversion, and connection
memory high controls the conversion method.
