DS33R11 Ethernet Mapper with Integrated T1/E1/J1 Transceiver
135 of 344
Register Name:
GL.CR1
Register Description:
Global Control Register 1
Register Address:
02h
Bit # 7 6 5 4 3 2 1 0
Name - - - - - REF_CLKO INTM RST
Default 0 0 0
Bit 2: REF_CLKO OFF (REF_CLKO) This bit determines if the REF_CLKO is turned off
1 = REF_CLKO is disabled and outputs an active low signal.
0 = REF_CLKO is active and in accordance with RMII/MII Selection
Bit 1: INT pin mode (INTM) This bit determines the inactive mode of the INT pin. The INT pin always drives low
when active.
1 = Pin is high impedance when not active
0 = Pin drives high when not active
Bit 0: Reset (RST). When this bit is set to 1, all of the internal data path and status and control registers (except
this RST bit), on all ports, are reset to their default state. This bit must be set high for a minimum of 100ns.
0 = Normal operation
1 = Reset and force all internal registers to their default values
Register Name:
GL.BLR
Register Description:
Global BERT Connect Register
Register Address:
03h
Bit # 7 6 5 4 3 2 1 0
Name - - - - - - - BLC1
Default 0 0 0 0 0 0 0 0
Bit 0: BERT Connect 1 (BLC1) If this bit is set to 1, the BERT is connected to Serial Interface 1. The BERT
transmitter is connected to the transmit serial port and receive to receive serial port. When the BERT is connected,
normal data transfer is interrupted. Note that connecting the BERT overrides a connection to the Serial Interface, if
a connection exists. When the BERT is disconnected, the connection is restored.
