Bit 6—Receive Interrupt Enable (RIE)
Bit 6 selects enabling or disabling of the receive data full interrupt request (RXI) and the receive
error interrupt request (ERI) when receive data is transferred from the receive shift register (RSR)
to the receive data register (RDR), and bit RDRF in the serial status register (SSR) is set to 1.
There are three kinds of receive error: overrun, framing, and parity.
RXI and ERI can be released by clearing bit RDRF or the FER, PER, or OER error flag to 0, or by
clearing bit RIE to 0.

Bit 5—Transmit Enable (TE)
Bit 5 selects enabling or disabling of the start of transmit operation.

Notes: 1. Bit TDRE in SSR is fixed at 1.
2. When transmit data is written to TDR in this state, bit TDRE in SSR is cleared to 0 and
serial data transmission is started. Be sure to carry out serial mode register (SMR)
settings, and setting of bit SPC32 in SPCR, to decide the transmission format before
setting bit TE to 1.
