TMP89FM42
RA001
Note 1: When a read instruction is executed on UART0CR2, bits 7 and 6 are read as "0".
Note 2: RTSEL can be set to two kinds of RT clocks for the even- and odd-numbered bits of the transfer frame. For details, refer to
"16.8.1 Transfer baud rate calculation method".
Note 3: For details of the RXDNC noise rejection time, refer to "16.10 Received Data Noise Rejection".
Note 4: When the STOP, IDLE0 or SLEEP0 mode is activated, the UART stops automatically but each bit value of UART0CR2
remains unchanged.
Note 5: When STOPBR is set to 2 bits, the first bit of the stop bits (during data receiving) is not checked for a framing error.
Note 6: To prevent RTSEL, RXDNC and STOPBR from being changed accidentally during the UART communication, the register
cannot be rewritten during the UART operation. For details, refer to "16.4 Protection to Prevent UART0CR1 and
UART0CR2 Registers from Being Changed".
Note 1: Set UART0CR1<RXE> and UART0CR1<TXE> to "0" before changing UART0DR. For the set values, refer to "16.8 Trans-
fer Baud Rate".
Note 2: When UART0CR1<BRG> is set to the TCA0 output, the value set to UART0DR has no meaning.
Note 3: When the STOP, IDLE0 or SLEEP0 mode is activated, the UART stops automatically but each bit value of UART0DR
remains unchanged.
