Notes: 1. The transmit data register empty bit (TDRE) in the serial status register (SSR) is fixed
Bit 4—Receive Enable (RE): Bit 4 enables or disables the start of a receive operation.

Notes: 1. When RE is cleared to 0, this has no effect on the SSR flags RDRF, FER, PER, and
Bit 3—Multiprocessor Interrupt Enable (MPIE): Bit 3 enables or disables multiprocessor
interrupt requests. This setting is valid only in asynchronous mode, and only when the
multiprocessor mode bit (MP) in the serial mode register (SMR) is set to 1. This bit is ignored
when COM is set to 1 or when bit MP is cleared to 0.

does not set status flags RDRF, FER, and OER in SSR. Until a multiprocessor bit value of 1
is received, the receive data full interrupt (RXI) and receive error interrupt (ERI) are
disabled and serial status register (SSR) flags RDRF, FER, and OER are not set. When the
multiprocessor bit receives a 1, the MPBR bit of SSR is set to 1, MPIE is automatically
cleared to 0, RXI and ERI interrupts are enabled (provided bits TIE and RIE in SCR3 are
set to 1), and setting of the RDRF, FER, and OER flags is enabled.
