(MSB) (LSB)
Sa8S Sa7S Sa6S Sa5S Sa4S SCLKM ESE –
SYMBOL POSITION NAME AND DESCRIPTION
Sa8S RCR2.7 Sa8 Bit Select. Set to one to report the Sa8 bit at the RLINK pin; set to zero
to not report the Sa8 bit.
Sa7S RCR2.6 Sa7 Bit Select. Set to one to report the Sa7 bit at the RLINK pin; set to zero
to not report the Sa7 bit.
Sa6S RCR2.5 Sa6 Bit Select. Set to one to report the Sa6 bit at the RLINK pin; set to zero
to not report the Sa6 bit.
Sa5S RCR2.4 Sa5 Bit Select. Set to one to report the Sa5 bit at the RLINK pin; set to zero
to not report the Sa5 bit.
Sa4S RCR2.3 Sa4 Bit Select. Set to one to report the Sa4 bit at the RLINK pin; set to zero
to not report the Sa4 bit.
SCLKM RCR2.2 SYSCLK Mode Select.
0 = if SYSCLK is 1.544 MHz
1 = if SYSCLK is 2.048 MHz
ESE RCR2.1 Elastic Store Enable.
0 = elastic store is bypassed
1 = elastic store is enabled
– RCR2.0 Not Assigned. Should be set to zero when written to.

(MSB) (LSB)
ODF TFPT T16S TUA1 TSiS TSA1 TSM TSIO
SYMBOL POSITION NAME AND DESCRIPTION
ODF TCR1.7 Output Data Format.
0 = bipolar data at TPOS and TNEG
1 = NRZ data at TPOS; TNEG=0
TFPT TCR1.6 Transmit Timeslot 0 Pass Through.
0 = FAS bits/Sa bits/Remote Alarm sourced internally from the TAF and
TNAF registers
1 = FAS bits/Sa bits/Remote Alarm sourced from TSER
T16S TCR1.5 Transmit Timeslot 16 Data Select.
0 = sample timeslot 16 at TSER pin
1 = source timeslot 16 from TS1 to TS16 registers
TUA1 TCR1.4 Transmit Unframed All Ones.
0 = transmit data normally
1 = transmit an unframed all one’s code at TPOS and TNEG
TSiS TCR1.3 Transmit International Bit Select.
0 = sample Si bits at TSER pin
1 = source Si bits from TAF and TNAF registers (in this mode, TCR1.6 must
be set to 0)
