89 D12 C16i
Master Clock (5 V Tolerant Input): Serial clock for shifting data in/out
on the serial streams. This pin accepts a 16.384 MHz clock.
91 D11 F0i
Master Frame Pulse (5 V Tolerant Input): In ST-BUS mode, this
input accepts a 61 ns wide negative frame pulse. In CT Bus mode, it
accepts a 122 ns wide negative frame pulse. In HMVIP mode, it
accepts a 244 ns wide negative frame pulse.
92 B13 C4i
/C8i HMVIP/CT Bus Clock (5 V Tolerant Input): When HMVIP mode is
enabled, this pin accepts a 4.096 MHz clock for HMVIP frame pulse
alignment. When CT Bus mode is enabled, it accepts a 8.192 MHz
clock for CT frame pulse alignment.
94 A13 F0o
Frame Pulse (5 V Tolerant Output): A 244 ns wide negative frame
pulse that is phase locked to the master frame pulse (F0i
).
95 C12 C4o
C4 Clock (5 V Tolerant Output): A 4.096 MHz clock that is phase
locked to the master clock (C16i
).

Serial Input Streams 0 to 15 / Frame Evaluation Inputs 0 to 15 (5 V
Tolerant I/O). In 2 Mb/s and HMVIP modes, these pins accept serial
TDM data streams at 2.048 Mb/s with 32 channels per stream. In
4 Mb/s or 8 Mb/s mode, these pins accept serial TDM data streams at
4.096 or 8.192 Mb/s with 64 or 128 channels per stream respectively.
In Frame Evaluation Mode (FEM), they are frame evaluation inputs.

mode, these pins accept serial TDM data streams at 2.048 or
4.096 Mb/s with 32 or 64 channels per stream respectively. In HMVIP
mode, these pins have a data rate of 8.192 Mb/s with 128 channels
per stream. In Frame Evaluation Mode (FEM), they are frame
evaluation inputs.

STio24 - 31 Serial Input Streams 24 to 31 (5 V Tolerant I/O). These pins are only
used for 2 Mb/s or 4 Mb/s mode. They accept serial TDM data streams
at 2.048 or 4.096 Mb/s with 32 or 64 channels per stream respectively.
9C1TMSTest Mode Select (3.3 V Input with internal pull-up): JTAG signal
that controls the state transitions of the TAP controller.
10 D1 TDi Test Serial Data In (3.3 V Input with internal pull-up): JTAG serial
test instructions and data are shifted in on this pin.
