Chip Select Bar/Jitter Attenuator Select
CSB:
This signal must be low during all accesses to the registers.
JAS:
In hardware mode, this pin is used as a jitter attenuator
select.
Low
→
Jitter attenuator is in the transmit path.
VDDIO/2
→
Jitter attenuator is not used.
High
→
Jitter attenuator is in the receive path.
Note: When left unconnected and in hardware mode, do not route
signals with fast transitions near JAS. This practice minimizes
capacitive coupling.

SCLK:
In the serial host mode, this pin is the serial clock. Data on
SDI is clocked on the rising edge of SCLK. The data is clocked on
SDO on the rising edge of SCLK if CLKE is high. If CLKE is low
the data on SDO is clocked on the falling edge of SCLK.
ALE:
In parallel Intel multiplexed mode, the address lines are
latched on the falling edge of ALE. Tie ALE pin high if using
nonmultiplexed mode.
ASB:
In parallel Motorola multiplexed mode, the address is
sampled on the falling edge of ASB. Tie ASB pin high if using
nonmultiplexed mode.
TS2:
In hardware mode, this pin signal is the most significant bit
position in
Table 5-11

Read Bar/Read Write Bar/Template Selection 1
RDB:
In Intel host mode, this pin must be low for read operation.
RWB:
In Motorola mode, this pin is low for write operation and
high for read operation.
TS1:
In hardware mode, this pin signal is the second significant bit
position in
Table 5-11
.

Serial Data Input/Write Bar/Data Strobe Bar/Template
Selection 0
SDI:
In the serial host mode, this pin is the serial input SDI. It is
sampled on the rising edge of SCLK.
WRB:
In Intel host mode, this pin is active low during write
operation. The data or address (multiplexed mode) is sampled on
the rising edge of WRB.
DSB:
In the parallel Motorola mode, this pin is active low. During a
write operation the data or address is sampled on the rising edge
of DSB. During a read operation the data (D[7:0] or AD[7:0]) is
driven on the rising edge of DSB. In the nonmultiplexed Motorola
mode, the address bus (A [5:0]) is latched on the falling edge of
DSB.
TS0:
In hardware mode, this pin signal is the least significant bit
position in
Table 5-11
