Implements imt::base::lib::remoting::DataReceiverIfc.

setInitialCrcValue()

void imt::base::lib::remoting::DataFrameCRC16CheckReceiveLayer::setInitialCrcValue

(

uint16_t const

initialCrcValue

)

Set the initial CRC value to increase robustness of CRC-16 checksum.

Older implementations used a default value of 0, which is the least robust. Recommendation: use 0xFFFF as initial value.

Parameters

initialCrcValue

Initial value for the CRC-16 checksum calculation.
