Notes:
1. The series resistors on the SPI lines are required for In-System Programming and On-chip
2. PA1 should be connected to SNGD when measuring V(RT
Debug support. The value of the series resistor depends on the application. A value of 10k will
ensure that programming and debugging operates correctly, but it must be determined by the
end user that this does not affect the normal operation of the SPI interface.
PA0 should be connected to SNGD when measuring V(RT
