Figure 9-3. Time Slot Assignment Table Showing MSC Configuration
Table 9-1 describes the elds in the time slot assignment table for receive (TSATRx) when
the MSC microcode is enabled.
Table 9-1. Time Slot Assignment Table Entry Fields for Receive (MSC)
Field
Description
V
Valid bit—The valid bit indicates whether this time slot is valid.
0 The data in this 8-bit time slot is totally ignored and not written to any buffer.
1 The data in this 8-bit time slot is valid and written to the current buffer, pointed to by the channel
pointer entry, after protocol processing (for example, zero deletion in HDLC).
W
Wrap bit—Identies the last entry in TSATTx.
0 This is not the last time slot in the frame.
1 The RISC processor wraps around and handles time slot 0 or the rst 8 bits transferred from the
TSA in the next request. The next request is identied by a frame synchronization pulse.
