Receive Alarm Indication Signal
T1 Mode: Toggles high when the receive Blue Alarm is detected.
E1 Mode: Toggles high when the receive AIS is detected.
64KCC Mode: This pin is in a high-impedance state.
6312kHz Mode: This pin is in a high-impedance state.
Active-Low Interrupt/Jitter Attenuator Clock Select 0

status registers. Active-low open-drain output.
JACKS0: Hardware Mode: Jitter Attenuator Clock Select 0. Set this pin high
for T1 mode operation when either a 2.048MHz, 4.096MHz, 8.192MHz, or
16.382MHz signal is applied at MCLK.
Transmit Mode Select 1. In Hardware Mode (BIS[1:0] = 11), this bit is used to
configure the transmit operating mode.
Transmit Mode Select 2. In Hardware Mode (BIS[1:0] = 11), this bit is used to
configure the transmit operating mode.
Three-State Control and Device Reset. A dual-function pin. A zero-to-one
transition issues a hardware reset to the DS26504 register set. Configuration
register contents are set to the default state. Leaving TSTRST high three-states
all output and I/O pins (including the parallel control port). Set low for normal
operation. Useful for in-board level testing.
Bus Interface Mode Select 1, 0. These bits select the processor interface mode
of operation.
BIS[1:0] : 00 = Parallel Port Mode (Multiplexed)
Data Bus D[7] or Address/Data Bus AD[7]/Receive Internal Termination
Disable
A[7]: In nonmultiplexed bus operation (BIS[1:0] = 01), it serves as the data bus
D[7].
AD[7]: In multiplexed bus operation (BIS[1:0] = 00), it serves as the
multiplexed address/data bus AD[7].
RITD: In Hardware Mode (BIS[1:0] = 11), internal receive termination is
disabled when RITD = 1.
