Hi All,
Anybody can help me to explain the sentence below, why this config can lead to race-free operation? Thanks.
"To ensure race-free operation, changes on TAP inputs (TMS and TDI) are clocked into the test logic defined by this standard on the rising edge of TCK while changes at the TAP output (TDO) occur on the falling edge of TCK"
from Pg20 of IEEE1149.1
