TABLE 9-14: COMM SCRIPT STATUS BLOCK

9.6 I

CM COMMUNICATIONS

CM refers to the Master mode of the I

C protocol. See the I

C specification for proto-

col details. In this mode, the PICkit™ Serial Analyzer will master the I

C bus only. It will

not respond as a slave. The control block of memory dedicated to communication

allows for setting of the bit rate and displaying event markers in the software windows.
