tored using the UART status register (UARTSR).
UART is controlled by the UART Control Registers (UARTCR1, UARTCR2). The operating status can be moni-
Note 1: When operations are disabled by setting TXE and RXE bit to “0”, the setting becomes valid when data transmit or receive
Note 2: The transmit clock and the parity are common to transmit and receive.
Note 3: UARTCR1<RXE> and UARTCR1<TXE> should be set to “0” before UARTCR1<BRG> is changed.
Note: When UARTCR2<RXDNC> = “01”, pulses longer than 96/fc [s] are always regarded as signals; when UARTCR2<RXDNC>
= “10”, longer than 192/fc [s]; and when UARTCR2<RXDNC> = “11”, longer than 384/fc [s].

complete. When the transmit data is stored in the transmit data buffer, the data are not transmitted. Even if data transmit is
enabled, until new data are written to the transmit data buffer, the current data are not transmitted.
