STo8 - 15
ST-BUS Output 8 to 15 (5 V Tolerant Three-state
Outputs):
Serial data Output 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.

STi0 - 15
ST-BUS Input 0 to 15 (5 V Tolerant Inputs):
Serial
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.

L1
F0i
Frame Pulse (5 V 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.

FE/HCLK
Frame Evaluation / HCLK Clock
(5 V Tolerant
Input):
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.

N1
CLK
Clock (5 V 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.
