JTAG Reset
This active Low input resets the JTAG controller. This input
is pulled up internally and may be left as a NC when not
used.
JTAG Test Mode Select Input
This input enables the JTAG serial port when active High.
This input is sampled on the rising edge of TCK. This input
is pulled up internally and may be left as a NC when not
used.
JTAG Test Clock
Data on TDI is valid on the rising edge of TCK. Data on
TDO is valid on the falling edge of TCK. When TCK is
stopped high or low, the contents of all JTAG registers re-
main unchanged. Tie pin low through a 10 KΩ resistor
when not used.
JTAG Test Data Output
JTAG test data is shifted out of the device on this pin. Data
is output on the falling edge of TCK. Leave as NC when not
used.
JTAG Test Data Input
JTAG test data is shifted into the device using this pin. The
pin is sampled on the rising edge of TCK. TDI is pulled up
internally and may be left as a NC when not used.
Reference Input
This pin must be tied to ground through 13.3 KΩ 1% resis-
tor. This pin is used to set the internal current level.
