CTEST_RFWEP
Register File Write Enable
When LOW, writes to the CPU register file are disabled.
This is used when the debug tool is active. This pin
should be held HIGH during normal operation.
Input
IDDTN
IDD Test
When LOW, all static power consuming devices are
turned off. This pin should be held HIGH during normal
operation.
Input
PMON_OUTP Process Monitor
Output for process monitor cell. This pin should be left
UNCONNECTED during normal operation.
Output
SE
Scan Chain Loading Enable
Assertion of this signal enables scan chain loading and
unloading. This pin should be held LOW during normal
operation.
Input
SI
Scan Chain Input
Inputs the scan chain. This pin should be left
UNCONNECTED during normal operation.
Input
SO
Scan Chain Output
Outputs the scan chain. This pin should be left
UNCONNECTED during normal operation.
Output
TN
3-State Outputs
Assertion of this input causes all of the EV4101 outputs
and bidirectional signals to be 3-stated. This pin should
be held HIGH for normal operation.
Input
TST
Scan Test Enable
When high, the SCAN test is enabled. This pin should be
held low during normal operation.
Input
