All open pins of the SiP can be used for application-specific purposes.
AVR: TXD, RXD, NRES and EN connected for LIN Master. The connection between the LIN-SBC
and the AVR requires the software being programmed correspondingly. System clock controlled
by external crystal.
LIN-SBC: Master application, 10k Master resistance connected via diode to VS, 1k master resis-
tance will be switched of via pin INH during sleep mode, local wake up via pin WAKE; watchdog is
enabled.
RF emissions: Best results for RF emissions will be achieved by connecting the blocking capaci-
tors of the microcontroller supply (C1 and C2) between the microcontroller pins and the
GND/PVCC line. See also
