A5: Address Bus bit5
In Intel/Motorola non-multiplexed interface mode, this signal is the address bus of the microcontroller interface.
In serial microcontroller interface mode, this pin should be connected to ground.
EQ2: Equalizer on/off for receiver2 in hardware control mode
0= short haul (10dB)
1= long haul (36dB for T1/J1, 43 dB for E1)
A4: Address Bus bit4
In Intel/Motorola non-multiplexed interface mode, this signal is the address bus of the microcontroller interface.
In serial microcontroller interface mode, this pin should be connected to ground.
RPD2: Power down control for receiver2 in hardware control mode
0= receiver 2 normal operation
1= receiver 2 power down
A3: Address Bus bit3
In Intel/Motorola non-multiplexed interface mode, this signal is the address bus of the microcontroller interface.
In serial microcontroller interface mode, this pin should be connected to ground.
EQ1: Equalizer on/off for receiver1 in hardware control mode
0= short haul (10dB)
1= long haul (36dB for T1/J1, 43 dB for E1)
A2: Address Bus bit2
In Intel/Motorola non-multiplexed interface mode, this signal is the address bus of the microcontroller interface.
In serial microcontroller interface mode, this pin should be connected to ground.
RPD1: Power down control for receiver1 in hardware control mode
0= receiver 1 normal operation
1= receiver 1 power down
A1: Address Bus bit1
In Intel/Motorola non-multiplexed interface mode, this signal is the address bus of the microcontroller interface.
In serial microcontroller interface mode, this pin should be connected to ground.
PATT21/PATT20: Transmit pattern select for channel 2
In hardware control mode, this pin selects the transmit pattern
00 = normal
01= All Ones
10= PRBS
11= transmitter power down
A0: Address Bus bit 0
In Intel/Motorola non-multiplexed interface mode, this signal is the address bus of the microcontroller interface.
In serial microcontroller interface mode, this pin should be connected to ground.

TERMn: Selects internal or external impedance matching for channel 1 and channel 2 in hardware control mode
0 = ternary interface with internal impedance matching network
1 = ternary interface with external impedance matching network in E1 mode; ternary interface with external impedance match-
ing network for receiver and ternary interface with internal impedance matching network for transmitter in T1/J1 mode.
(This applies to ZB die revision only.)
In software control mode, this pin should be connected to ground.
JA[1:0]: Jitter attenuation position, bandwidth and the depth of FIFO select for channel 1 and channel 2 (only used
in hardware control mode)
