11.10.2.3 CONFIGURATION CONSIDERATIONS
The PICkit Serial Analyzer can be configured to operate as LIN bus master, monitor or
both.
MASTER
To configure the PICkit Serial Analyzer to perform as LIN bus master, the host must
write the CONTROL_BLOCK to specify:
1. Default baud rate
2. LIN adapter ‘Chip Select’ line state
Optionally,
1. Set ‘receive enable’ Configuration bit to allow the PICkit Serial Analyzer to
receive RX data and report it to the host
2. Enable desired event markers
