Cautions 1. Be sure to read the UC0RX register even when a reception error occurs. If the UC0RX register
2. Reception is performed assuming that there is only one stop bit. A second stop bit is ignored.
3. When reception is completed, read the UC0RX register after the reception complete interrupt
4. If the receive completion processing (INTUC0R signal generation) of UARTC0 conflicts with
CHAPTER 17 ASYNCHRONOUS SERIAL INTERFACE C (UARTC) (
is not read, an overrun error occurs during reception of the next data, and reception errors
continue occurring indefinitely.
request signal (INTUC0R) has been generated, and clear the UC0RXE bit to 0. If the UC0RXE
bit is cleared to 0 before the INTUC0R signal is generated, the read value of the UC0RX
register cannot be guaranteed.
setting the UC0PWR bit or UC0RXE bit to 0, the INTUC0R signal may be generated in spite of
there being no data stored in the UC0RX register.
To complete reception without waiting for INTUC0R signal generation, be sure to clear (0) the
interrupt request flag (UC0RIF) of the UC0RIC register, after setting (1) the interrupt mask flag
(UC0RMK) of the interrupt control register (UC0RIC) and then set (1) the UC0PWR bit or
UC0RXE bit to 0.
