On-Chip Emulation Module
JTAG PORT/onCE MODULE INTERACTION
In Òstep nÓ the external command controller verifies that the OS[1:0] bits have the value
11, indicating that the chip has entered debug mode. If the chip has not yet entered
debug mode, the external command controller goes to Òstep bÓ, Òstep cÓ etc. until debug
mode is acknowledged.
