Error in GetCourseTrimEnabled()

[asuarez-gh]

In the function

bool RTCC_MCP7940N::GetCourseTrimEnabled() { return this->GetFlag(0x08, B100); }

you maybe reading from the wrong register. Register 8 holds the trim value but register 7 holds the enable bit value. You had it correct in the set function.

void RTCC_MCP7940N::SetCourseTrimEnabled(bool enabled) { this->SetBits(0x07, B100, enabled << 2); }
