The NRN command reads or writes any of the seven registers in the nibble register memory map on the
NT1 side U-Interface Transceiver. The command defaults to a read of the speciÞed register. The register
number is entered as a decimal number. When a valid hexadecimal character follows the register number
written to, the speciÞed register is updated and the contents are echoed to the terminal. The eoc register,
R6, is accessed by entering ÒNRN 6 [ddd].Ó This reads/writes the eoc (R6) register, which is a 12-bit register
appearing in the nibble register memory map.

Bits that are read only/write only may not necessarily reßect the value written to them when
echoed to the terminal.
All three digits required, no spaces, for write to nibble register 6.
Bits that are read only/write only may not necessarily reßect the value written to them when
echoed to the terminal.
