Note:
The MCP3421 device supports the I
2
C bus data rate up to 3.4 MHz, but the 
current version of the PICkit Serial Analyzer supports the I
2
C bus data rate 
up to 400 kHz only.
Note:
The MCP3421 SOT23-6 Evaluation Board has its own pull-up resistors, 
therefore, you don’t need additional pull-up resistors from the PICkit Serial 
Analyzer.
