Note 1: The OERR and UERR flags are cleared by reading SIO0SR.
Note 2: The REND flag is cleared by reading SIO0BUF.
Note 3: Writing "00" to SIO0CR<SIOM> clears all the bits of SIO0SR to "0", whether the serial interface is operating or not. When
STOP, IDLE0 or SLEEP0 mode is activated, SIOM is automatically cleared to "00" and all the bits of SIO0SR are cleared
to "0".
Note 4: Bit 1 to 0 of SIO0SR are read "0".
