PRELIMINARY
6.7
6.7.1
All PCM data lines are in a high impedance state after the reset process. If they are
configured (data rate, bit shift) they can be enabled with the standby command. During
the normal operation the PCM lines can be enabled or disabled with the standby
command. If the lines are disabled the device works internally like an active device.
Example:
Set all output PCM lines to high impedance.
6.7.2
The data rate range command is necessary to optimize the minimum delay feature. After
the reset process the device assumes a bit rate of 2.048 Mbit/s for all PCM lines. The
command must be issued if other data rates are used.
Example (8-bit µP interface):
1. Specify that only 2.048 Mbit/s and 4.096 Mbit/s are used for following Set Bit Rate
2. Set bit rate of 4.096 Mbit/s on local bus input line 8 and local bus output line 1
Example (16-bit µP interface):
