◆ shiftJustification

uint8_t UART_Object::shiftJustification

This is the number of bits the read data needs to be shifted. This is calculated using the data length. When data of fewer than eight bits in length is received, it is left-justified in SCIRD and padded with trailing zeros. Data read from the SCIRD should be shifted by software to make the received data rightjustified.
