Receive PRM C/R Bit Control Pin for T1.403 Mode. 0 (GND) = only
respond to PRM with C/R bit set to one. N/C (Floating) = only respond
to PRM with C/R bit set to zero.
Address Select Bit Control Pin for TR54016. 0 (GND) = respond to
address B (or Y). N/C (Floating) = respond to address A (or Z).
Transmit PRM C/R Bit Control Pin for T1.403 Mode. 0 (GND) = force
C/R bit to one in outgoing PRM. N/C (Floating) = force C/R bit to zero
in outgoing PRM.
Idle Code Select Bit Control Pin for TR54016. 0 (GND) = 7E (h)
N/C (Floating) = FF (h).
UB5 pin allows the user to select between the hardware
and software operating modes. The hardware mode is
provisioned by connecting the UB5 pin to GND. If the
UB5 pin is left floating, the software mode is enabled for
serial port operations.
DS2282 will continue to monitor and supply the FDL
data stream messages automatically without any inter-
action by the user. B8ZS, T1.403, and 54016 operating
modes are configured by external pin connections,
along with the PRM C/R bit control, address, and idle
code selects indicated by the hardware mode table.
The external UB pins (1–6) are read during power up or
reset events.
defined hardware operating mode can be changed in
software via the corresponding register bits.
