Bit 5
T1 or E1 Chip Determination Bit. Set to 1.
0 = T1 chip
1 = E1 chip
Bit 6. See
Bit 5. See
Bit 4. See
Chip Revision Bit 3. MSB of a decimal code that represents the chip
revision.
Chip Revision Bit 2.
Chip Revision Bit 1.
Chip Revision Bit 0. LSB of a decimal code that represents the chip
revision.
RSYNC Multiframe Function. Only used if the RSYNC pin is
programmed in the multiframe mode (RCR1.6=1).
0 = RSYNC outputs CAS multiframe boundaries
1 = RSYNC outputs CRC4 multiframe boundaries
RSYNC Mode Select.
0 = frame mode (see the timing in Section 18)
1 = multiframe mode (see the timing in Section 18)
RSYNC I/O Select. (Note: this bit must be set to zero when RCR2.1=0).
0 = RSYNC is an output (depends on RCR1.6)
1 = RSYNC is an input (only valid if elastic store enabled)
Not Assigned. Should be set to zero when written.
Not Assigned. Should be set to zero when written.
Frame Resync Criteria.
0 = resync if FAS received in error 3 consecutive times
1 = resync if FAS or bit 2 of non-FAS is received in error three
consecutive times
Sync Enable.
0 = auto resync enabled
1 = auto resync disabled
Resync. When toggled from low to high, a resync is initiated. Must be
cleared and set again for a subsequent resync.
