in the IMS register.
data input stream. These streams may have data rates
of 2.048, 4.096 or 8.192 Mb/s, depending upon the
value programmed at bits DR0 - 1 in the IMS register.
Frame Pulse (5V Tolerant Input): When the WFPS
pin is low, this input accepts and automatically
identifies frame synchronization signals formatted
according to ST-BUS and GCI specifications. When the
WFPS pin is high, this pin accepts a negative frame
pulse which conforms to WFPS formats.
When the WFPS pin is low, this pin is the frame
measurement input. When the WFPS pin is high, the
HCLK (4.096MHz clock) is required for frame
alignment in the wide frame pulse (WFP) mode.
Clock (5V Tolerant Input): Serial clock for shifting data
in/out on the serial streams (STi/o 0 - 15). Depending
upon the value programmed at bits DR0 - 1 in the IMS
register, this input accepts a 4.096, 8.192 or 16.384
MHz clock.
Test Mode Select (3.3V Input with internal pull-up):
JTAG signal that controls the TAP controller state
transitions.
Test Serial Data In (3.3V Tolerant Input with internal
pull-up): JTAG serial test instructions and data are
shifted in on this pin.
