3.17 System Bus Registers
Controlled TSLIP Event—TUSLIP and TFSLIP event status are latched active-high when
TFSLIP
transmit slip error is detected. Either event reports a TSLIP error in ISR5 [addr 006].
Active-high hold interval is defined by LATCH_ERR [addr 046].
Two types of errors are detected:
1.
2.
TSBI Mode
Normal
Short
Elastic
Bypass
NOTE(S):
(1)
Most recent slip error direction is reported in TSDIR.
2. TFSLIP not applicable (read zero value) if TSLIP bypassed or configured as elastic
store. TUSLIP not applicable if TSLIP bypassed. In Short-Delay mode, if the bus
clock is faster than the receive clock, the system bus resynchronizes and USLIP is be
reported. If the receive clock is faster, RSLIP reverts to Normal mode and reports
FSLIP errors.
Uncontrolled TSLIP Event—See TFSLIP description.
TUSLIP
Receive Slip Direction—RSDIR is updated each time an RSLIP error is latched in RFSLIP or
RSDIR
RUSLIP, and indicates which direction the slip occurred.
3-124
Fully Integrated T1/E1 Framer and Line Interface
FSLIP = Controlled frame slip on TX data output. FSLIP affects transmit
time slot data, but does not change the transmit timebase or frame
alignment.
USLIP = Uncontrolled 1 to 256 bit slip on TX data. USLIP affects both
time slot data and frame alignment. TUSLIP and TFSLIP status depends
on the transmit system bus configuration [TSB_CR; addr 0D4].
