3.19
The SCF5250 complies with the IEEE 1149.1A JTAG testing standard. The JTAG test pins are multiplexed
with background debug pins.
3.20
The clock and reset signals configure the SCF5250 processor and provide interface signals to the external
system.
3.20.1
Asserting RSTI causes the SCF5250SCF5250 to enter reset exception processing. When RSTI is
recognized, the data bus is tri-stated.
