Figure 13-7 Generation of Overrun Error
Note:Receive operations are disabled until the overrun error flag UART2SR<OERR> is cleared.
13.9.4 Receive Data Buffer Full
Loading the received data in RD2BUF sets receive data buffer full flag UART2SR<RBFL> to "1". The
UART2SR<RBFL> is cleared to “0” when the RD2BUF is read after reading the UART2SR.
Figure 13-8 Generation of Receive Data Buffer Full
Note:If the overrun error flag UART2SR<OERR> is set during the period between reading the UART2SR and read-
ing the RD2BUF, it cannot be cleared by only reading the RD2BUF. Therefore, after reading the RD2BUF,
read the UART2SR again to check whether or not the overrun error flag which should have been cleared still
remains set.
13.9.5 Transmit Data Buffer Empty
When no data is in the transmit buffer TD2BUF, that is, when data in TD2BUF are transferred to the transmit
shift register and data transmit starts, transmit data buffer empty flag UART2SR<TBEP> is set to “1”. The
UART2SR<TBEP> is cleared to “0” when the TD2BUF is written after reading the UART2SR.
