The TE3-CHATT will NOT generate a ’Transmit Command Complete’ interrupt vector
after this command is programmed.
Transmit Update FNUM
The
CSPEC_MODE_XMIT.FNUM in the internal channel database, which allows to change
dynamically the number of idle flags that are inserted between two frames.
The TE3-CHATT will NOT generate a ’Transmit Command Complete’ interrupt vector
after this command is programmed.
Transmit Idle
The ’Transmit Idle’ command starts the TE3-CHATT to send the value
CSPEC_MODE_XMIT.TFLAG in the time slots of the selected channel. This command
can only be given if a channel is turned off.
The TE3-CHATT will NOT generate a ’Transmit Command Complete’ interrupt vector
after this command is programmed.
Transmit Debug
The ’Transmit Debug’ command allows to read back the current settings of the internal
channel database. After the ’Transmit Debug’ command has been programmed system
software can read back the current values of the channel specification registers. Register
CSPEC_FTDA contains the value of the next transmit descriptor.
The TE3-CHATT will NOT generate a ’Transmit Command Complete’ interrupt vector
after this command is programmed.
Note: The setting of the internal channel database is not copied into the channel
6.3
Receive Init
Before a ’Receive Init’ command is given, the TE3-CHATT will not process data for a
channel. After the ’Receive Init’ command the channel database of the affected channel
is initialized according to the parameters programmed in channel specification registers.
After initialization data received in those time slots assigned to the selected channel is
processed and stored in the internal receive buffer. The data management unit starts
storing this data in the linked list which starts at CSPEC_FRDA. The protocol machine
deformats and checks data according to the given channel parameters.
Data Sheet
specification registers and therefore the values read can not be used to program
another channel. After system software has used the ’Transmit Debug’ command
it must reprogram the channel specification registers to setup a new channel.
