VIII - INTERNAL REGISTERS (continued)
LP (i)
N.B. If DIN4 and DIN5 are GCI Multiplexes : then ST(4)1 = ST(4)0 = 0 and ST(5)1 = ST(5)0 = 0 normally.
VIII.5 - Output Multiplex Configuration Register 0 - OMCR0 (08)H
See definition in next Paragraph.
VIII.6 - Output Multiplex Configuration Register 1 - OMCR1 (0A)H
ST(i)0 : STEP0 for each Output Multiplex i(0
ST(i)1 : STEP1 for each Output Multiplex i(0
DEL(i); : DELAYED Multiplex i(0
OMV (i) : Output Multiplex Validated 0/7
N.B. If DIN4 and DIN5 are GCI Multiplexes : then ST(4)1 = ST(4)0 = 0 and ST(5)1 = ST(5)0 = 0 normally.

: LOOPBACK 0/7
LPi = 1, Output Multiplex i is put instead of Input Multiplex i (0 i 7). LOOPBACKis transparent
or not in accordance with OMVi (bit of Output Multiplex Configuration Register).
LPi = 0, Normal case, Input Multiplex i(0
When IMTD = 0 (bit of SMCR), DEL = 0 is not taken into account by the circuit.
1/2 bit time 244ns if TDM at 2048 kHz,
1/2 bit time 122ns if TDM at 4096 kHz.
OMVi =1, condition to have DOUTi pin active (0
OMVi =0, DOUTi pin is High Impedance continuously (0
When SI = 0 (bit of CMDR, variable delay mode) :
IMTD = 1, the minimum delay through the matrixmemoryis three time slots whateverthe selected
TDM output.
IMTD = 0, the minimum delay through the matrix memory is two time slots whatever the selected
TDM output.
When IMTD = 0, the input TDMs cannot be delayed versus the frame synchronization (Use
of IMCR is limited) and the output TDMs cannot be advanced versus the frame
synchronization.(Use of OMCR is limited).

Each bit is transmitted on the rising edge of the double clock without delay.
Bit 0 is defined by Frame synchronization Signal.
Each bit is transmitted with 1/2 bit-time delay.
Each bit is transmitted with 1 bit-time delay.
Each bit is transmitted with 2 bit-time delay.
Each bit is transmitted with 1/2 bit-time advance.
Each bit is transmitted with 1 bit-time advance
Each bit is transmitted with 2 bit-time advance.
