ENCODER/DECODER CONFIGURATION: Selects the operating mode of the
controller-encoder/decoder functions and their interface. See table below and pin
descriptions for the monitor pins, TXD, TCK, TEN, LBC, RXD, RCK, CRS and COL:
E/D CNF 1

Normal NICE: Internal encoder/decoder active.
Monitor pins inactive.
01
NICE + Monitor: Internal encoder/decoder active.
Monitor pins outputting all controller/encoder/
decoder interface signals
10
Encoder/Decoder Bypass: Internal encoder/
decoder not used. Monitor pins can be used to
interface controller to external encoder/decoder.
11
Encoder/Decoder Test: Controller inactive,
encoder/decoder active. Monitor pins used to test
encoder/decoder.

POWER DOWN: When set high, enables power to the chip for all functions; when set low,
places chip in power down mode for power conservation.

REGISTER BANK SELECT: Provides the indirect address for selection of one of the three
sets of registers to access when the physical register address is xxx8H–xxxFH.
The lower 7 registers are not bank-selectable. See table:

BYTE ORDER CONTROL: Selects byte lane ordering for packet data in the buffer (applies
only in System Word Mode). In both Most..Least and Least..Most modes, the first and second
bytes of the packet will appear in the same word on the system bus. When this bit is high (M..L
mode), the first and all odd-numbered bytes of a packet and its header will appear on the high
byte of the system bus. Note that header bytes are also swapped.
