Test Mode Select: The signal present on this lead is
used to control boundary scan test operations. This
lead is provided with an internal pull-up resistor.
Test Data Input: Serial data input for boundary scan
test messages. This lead is provided with an internal
pull-up resistor.
mation is clocked out on falling edges of TCK.
Test Clock: The input clock for boundary scan test-
ing. The TDI and TMS states are clocked in on its ris-
ing edges. This lead is provided with an internal pull-
up resistor.
Test Reset: When an active low signal is applied to
this lead, the M13X Test Access Port (TAP) controller
resets and the boundary scan is disabled. The con-
troller is also reset by holding the TMS signal lead
high for at least five rising clock edges of TCK. Dur-
ing power-up of the M13X, this lead must be held
low, to reset the TAP controller. Failure to do so may
cause the TAP controller to take control of the M13X
output leads. When the boundary scan feature is not
used, this lead must be tied low. The software reset
function in register 1FH does not affect the boundary
scan logic. This lead is provided with an internal pull-
up resistor.
