Reserved bits.
Bit is set to 1 to indicate that a misrouted cell has been received. Cleared
by a write operation.
VCI Records per Page Selection bit 1. In conjunction with VRPS0, this bit
selects the number of VCI records per page (VRP) to be either 256, 512,
1024 or 128.
VRPS1,VRPS0= 0,0: VRP is 256
VRPS1,VRPS0= 0,1: VRP is 512
VRPS1,VRPS0= 1,0: VRP is 1024
VRPS1,VRPS0= 1,1: VRP is 128
VCI Records per Page Selection bit 0. In conjunction with VRPS1, this bit
selects the number of VCI records per page (VRP) to be either 256, 512,
1024 or 128.
Ignore translation record I-bit. When set to 1, connections marked as I-
bit=1 in the translation records will be treated as if I-bit=0.
CRC-4 calculation is inverted to produce an incorrect CRC-4 value for the
CellBus Bus Routing Header. This bit is intended for test purposes.
When set to 1, this bit enables CUBIT- Pro to compute the CRC-4 field H3-
H0 in the CellBus Bus Routing Header for all cells going into the cell inlet
FIFO. If set to 0, then CRC-4 is computed only for loopback cells. The
default at power-up is CRC4EN=0.
If this bit is set to 1, the CONGOUT output signal is an indication of actual
or impending congestion at the receiving CUBIT- Pro . If set to 0,
CONGOUT is a GTL-to-CMOS translation of the CellBus bus signal
CBCONG. EBP must be set to 1 to enable the ACK and NACK functions of
CIF1 and CIF3, respectively, when operating in UTOPIA or back-to-back
modes. Also, EBP must be set to 1 in order to tri-state CONGOUT when
ONLINE=0. The default at power-up is EBP=0.
cells. If set to 0, the CUBIT- Pro TXC-05802 uses CUBIT TXC-05801 OAM
routing. The default at power-up is OAMRMEN=0.
Reserved bit.
Time-out counter preset value for bus access watchdog timer. If timer
expires after a request is made, and before a grant is received, alarm bit
NOGRT is set. Each count represents one bus frame cycle.
