Reception
On detection of the start bit, the UartRxBusy bit is set. On detection of the stop bit, the received data are
transferred from the internal shift register to the register RegUartRx. At the same time, the UartRxFull bit is set
and an interrupt is generated on Irq_uart_Rx. This indicates that new data is available in RegUartRx. The timing
diagram is shown in Figure 15-2.
The UartRxFull bit is cleared when RegUartRx is read. If the register was not read before the receiver transfers a
new word to it, the bit UartRxOErr (overflow error) is set and the previous contents of the register are lost.
UartRxOErr is cleared by writing any data to RegUartRxSta.
The bit UartRxSErr is set if a start error has been detected. The bit is updated at data transfer to RegUartRx.
The bit UartRxPErr is set if a parity error has been detected, i.e. the received parity bit is not equal to the
calculated parity of the received data. The bit is updated at data transfer to RegUartRx.
The bit UartRxFErr in RegUartRxSta shows that a frame error has been detected. No stop bit has been detected.
