7.4.6 Receive operation
When the receive enable bit is set to “1,” the UARTi enters the reception enabled state and reception starts
at detecting ST. The receive operation is described below.
The receive complete flag is cleared to “0” when the low-order byte of the UARTi receive buffer register
is read out. Figure 7.4.11 shows an example of receive timing when the transfer data length is 8 bits.
synchronously with the transfer clock’s rising.
When one set of data has been prepared, in other words, the shift according to the selected data format
has been completed; the UARTi receive register’s contents are transferred to the UARTi receive buffer
register.
request occurs and its interrupt request bit is set to “1.”
The contents of UARTi receive register are shifted by 1 bit to the right.
