Connection of transmission
OCD’s two
-wire communication interfaces use the Open-Drain Method (Wire-AND Bi-Directional I/O).
Normally, it is recomme
nded to place a resister greater than 4.7kΩ for the DSCL and DSDA respectively.
The capacitive load is recommended to be less than 100pF. Outside these ranges, because the
communication may not be accomplished, the connection to Debug mode is not guaranteed.
