FUNCTION
IFSS
7
Internal Frame-Sync Select
0 = TSYNC normal
1 = if TSYNC is in the INPUT mode (TSIO = 0), then TSYNC is internally
replaced by the recovered receive frame sync. The TSYNC pin is ignored
1 = if TSYNC is in the OUTPUT mode (TSIO = 1), then TSYNC outputs the
recovered multiframe frame sync
TFPT
6
Transmit Time Slot 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
AEBE
5
Automatic E-Bit Enable
0 = E-bits not automatically set in the transmit direction
1 = E-bits automatically set in the transmit direction
TUA1
4
Transmit Unframed All Ones
0 = transmit data normally
1 = transmit an unframed all-ones code
TSiS
3
Transmit International Bit Select
0 = sample Si bits at TSER pin
1 = source Si bits from TAF and TNAF registers (In this mode, TCR.6 must be
set to 0)
TSA1
2
Transmit Signaling All Ones
0 = normal operation
1 = force time slot 16 in every frame to all ones
TSM
1
TSYNC Mode Select
0 = frame mode (see the timing diagrams in Section 24.2)
1 = CAS and CRC4 multiframe mode (see the timing diagrams in Section 24.2)
TSIO
0
TSYNC I/O Select
0 = TSYNC is an input
1 = TSYNC is an output
Note: See Figure 24-9 for more details about how the transmit control register affects DS21Q59 operation.
